Yung number 1, we can express this in two variables. We have two equations: x + y = 55 4x + 5 = y By substitution: x + 4x + 5 = 55 5x = 50 x = 10 By substituting the 2nd equation, the answer is 45, which is the value of y.
Hello po sir. I am an Aeronautical Engineering student. Sobrang sobrang anxious ko po sa math to the point na nafefeel ko na nasusuka ako at nanginginig kapag alam ko na may haharapin akong math mapa lecture, activity, quiz or etc. sir. May maiaadvice po ba kayo sakin? Prelims grade ko sa math for engineering and calculus is bagsak po, which is nakakadagdag sa anxiety ko at pressure.

Based lang po saakin as defined sa video, 'y' represents 'tens digit' or yung pangalawang digit, while yung 'x' is the first digit. Para easy to understand lang, i'll just illustrate 10y+x Example: '51' where; y =5 and x = 1 10(5) + 1 = 51
iba yung vaue sa smaller at larger number ko sa no.1 pero ang total is 55 meron ba mali sa aking answer? like look let x be the smaller let y be the larger the sum of two numbers is 55 so y + x =55 so proceed sa problem so 4 times the smaller is 5 less than the larger y=4x-5 so meron na tayong value sa y substitute sa the sum of two numbers na equation nation so y+x=55 4x-5+x=55 5x-5=55 so transfer natin dahil na iba si 5 5x=55+5 5x=60 tapos remove si 5 so ayon devide x= 12 nakuha na natin value ni x value naman ni y so sa equation na naman ulit na may total na 55 at substitute na natin si x y+x=55 y+12=55 transfer si 12 y= 55-12 y= 43 so ayun check nation kong tama ba substitute ang dalawa y+x=55 43+12=55 so tama akoing answer pero mag kaiba tayu ng smaller at larger number haha nalilito na ako ano ba talaga hahaha pakitulong
Ganyan rin po saakin noong una hehe, pero I notice na may nabago ako sign kaya naging 12. Bali ganito ko siya na solve X = smaller Y = Larger X+Y=55 So ang sabi nga 4 times the smaller is 5 less than the larger which means 4 times the smaller = 4x is = "=" Bali may other video si kuya na-mention niya na kapag naka encounter ng "is" it indicates na = equal sign siya. 5 less than the larger = Y - 5 Putting it all together 4x = Y - 5 Bali I-transpose si 5 sa 4x, although not sure ako if tama ba ito sa math rule pero at the end it makes sense naman sa pag solve 5+4x = Y. or simply, Y = 4x +5 Let's solve the equation X + Y = 55 substitute Y = 4x + 5 X+ 4x + 5 = 55 transpose or ilipat si +5 magiging -5 5x= 55-5 5x= 50 /5 /5 cancel 5 para matira si x X= 10. Bali noong una kasi instead na Y = 4x + 5, is 4x - 5 siya hehe, kaya nakuha ko rin 12.
Kulang kulang po ung explanation sir. And medjo mahirap din pong intindihin yung word problem. Kagaya ng #2. Ganito po cguro dapat yan sir. #2.) The sum of two numbers is 17. One number is 4 less than twice the other. Find the numbers. Ganyan po dapat cguro sir. Inabot po ako ng mga 3 hours na paulit ulit initindi yung tutorial nyo sa video na to kasi napakahirap pong intindihin kasi kulang kulang po yung explanation. Pasenxa na po sir, pero gusto ko lang pong matuto.
kahit 2 problems lng sana sir, basta dahan2 lng sa representation sa unknown
Yung number 1, we can express this in two variables. We have two equations:
x + y = 55
4x + 5 = y
By substitution:
x + 4x + 5 = 55
5x = 50
x = 10
By substituting the 2nd equation, the answer is 45, which is the value of y.
salamat marami sir.isa isa ko nang pinapanuod lahat vids.dito.HAHAHA more lessons to come po,parequest na din po clock problems,salamat
San ba nakuha yung 10y sa number 5? Di naman inexplain

@@rociv7794 ganon ba? at least naman masaya kana dyan goodluck lods kaya mo yan
Sana dahan dahan po para mas maintindihan hehe
Salamat sir ikaw talaga ang teacher naminn
masyadong mabilis sir, sana na explain dahan2 kung paano pag analyze sa problems at kung ano yung "unknown"sa problem..step by step sana sir...salamat

Solid di kona need online class ito lang solved na
ambilis sir haha
Yanga e
Tanong ko lng. Tuwing kelan ba gagamit ng ibang variables? Like pag X ba lahat or merong Y? Nalilito talaga ako huhu
nalito ako sir hinde mona agad inadd ang dalawang light terms then nalagyan pa ng parenthesis which is tina times sa katatabi nitong number...
Sana ganoon kadali maganalyza for me ng algebraic problems. Hahaha!
Hello sir, sa problem no 5, ask ko lang saan po nakuha yung 10y +x? (original number) Thanks. :)
Based lang po saakin
as defined sa video, 'y' represents 'tens digit' or yung pangalawang digit, while yung 'x' is the first digit.
Para easy to understand lang, i'll just illustrate
10y+x
Example: '51'
where; y =5 and x = 1
10(5) + 1 = 51

Thanks po
Thank youu sir!
iba yung vaue sa smaller at larger number ko sa no.1 pero ang total is 55 meron ba mali sa aking answer? like look
let x be the smaller
let y be the larger
the sum of two numbers is 55 so
y + x =55
so proceed sa problem
so 4 times the smaller is 5 less than the larger
y=4x-5
so meron na tayong value sa y
substitute sa the sum of two numbers na equation nation so
y+x=55
4x-5+x=55
5x-5=55
so transfer natin dahil na iba si 5
5x=55+5
5x=60
tapos remove si 5 so ayon devide
x= 12
nakuha na natin value ni x value naman ni y so sa equation na naman ulit na may total na 55 at substitute na natin si x
y+x=55
y+12=55
transfer si 12
y= 55-12
y= 43
so ayun check nation kong tama ba substitute ang dalawa
y+x=55
43+12=55
so tama akoing answer pero mag kaiba tayu ng smaller at larger number haha
nalilito na ako ano ba talaga hahaha
pakitulong
Ganyan rin po saakin noong una hehe, pero I notice na may nabago ako sign kaya naging 12.
Bali ganito ko siya na solve
X = smaller
Y = Larger
X+Y=55
So ang sabi nga 4 times the smaller is 5 less than the larger
which means
4 times the smaller = 4x
is = "="
Bali may other video si kuya na-mention niya na kapag naka encounter ng "is" it indicates na = equal sign siya.
5 less than the larger = Y - 5
Putting it all together
4x = Y - 5
Bali I-transpose si 5 sa 4x, although not sure ako if tama ba ito sa math rule pero at the end it makes sense naman sa pag solve
5+4x = Y. or simply, Y = 4x +5
Let's solve the equation
X + Y = 55
substitute Y = 4x + 5
X+ 4x + 5 = 55
transpose or ilipat si +5 magiging -5
5x= 55-5
5x= 50
/5 /5
cancel 5 para matira si x
X= 10.
Bali noong una kasi instead na Y = 4x + 5, is 4x - 5 siya hehe, kaya nakuha ko rin 12.
@@itsyou9547 ah okay2 thankyou soo mali yong answer ko or okay lang na ganun din ang answer? ;>
pano po naging 10y + x yung original number sa problem 4? paki-elaborate lang po.
Dapat sana ung detailed, hindi ko magets e to the point na mapapasabi ng "paano nangyari yun?" HAHAHA
Kulang kulang po ung explanation sir. And medjo mahirap din pong intindihin yung word problem. Kagaya ng #2. Ganito po cguro dapat yan sir.
#2.) The sum of two numbers is 17. One number is 4 less than twice the other. Find the numbers.

Y=55-x
wait where did you get 10x+y?
on question no.5
10(x) tens digit
+ y (units or ones digit).
So pag may 4 tens and 6 ones ka, 40 + 6 = 46
Thank you po!
Masyado po mabilis,pero salamat po
Ang no. 4 ay hindi ko pa naiintindihan 😅😅😢😢
andaming ads😭😭😭
pano ba hahaha hirap ako sa problemmss
ang bilis😭
bilis mag turo, walang kwenta
