Grade 10 Solving Linear Systems by Graphing
Вставка
- Опубліковано 3 сер 2024
- What does solving a linear system mean? How do we find the solution to a linear system by graphing? In this lesson I will solve some basic linear equations by graphing and then will solve a word problem involving mixtures and one using distance speed and time using graphing skills.
Thank you very much Ms. Havrot! There is a small error in the second last question, the intersection point is (80,120) instead of (120,80).
You are absolutely correct! Thanks for finding this mistake. 😊
So happy to have found this channel. Just what I needed! Thank you!! :)

My dear Math Sensei @26:48 I found y=1.35, by substitution as you mentioned it; 1) x + y = 6 then x = 6 - y, if we replace the x in the second equation which is 70x + 50y = 393 it will be 70(6 - y) + 50y = 393 ↓ 420 - 70y + 50y = 393 ↓ 420 - 393 = 20y ↓ 27/20 = y therefore y= 1.35, if Pythagoras doesn't lie. 😅 Then x + y = 6 ↓ x = 6 - 1.35 therefore x = 4.65.
Good job! Definitely much more accurate than trying to use the graph, isn’t it?
@@mshavrot_math Absolutely! Thank you for sharing your wisdom with us!!!
I don’t know if you are seeing this message or reply me back. I just want to say thank you for sharing all the knowledge and that I love you your voice and way of explaining.
How sweet of you to comment! I certainly read and do my best to answer all comments and questions. Thanks for watching and I wish you all the best this year!
@@mshavrotscanadianuniversit6234 thanks for acknowledging. I send you love and respect to you. ❤️Is it possible anyway that I can get advice or solution of any particular problem?
You can always ask!
thank you so much, also my grandpa is from kirkland lake, his name is Arthur Fong, it would be cool if you knew him :)
Kirkland Lake is a small place! I know OF your grandfather, but he was a bit older than me by probably 12 years?
He probably knew my dad Edward Havrot. He was the mayor of KL and also a member of parliament provincially for many years. : )
My mother is friends with Raymonde Fong whose husband has a brother Arthur.
The answer you got is wrong
Could you be a little more specific about what question and at what time in the video you think there is a mistake?
If you are referring to (80, 120) vs (120, 80) I would remind you to read other comments as someone had politely asked about that a year ago.
