    Thank you! Sorry about that! I've added annotations to show the correct work and answer.

    THANK YOU!!!! After 4 weeks of not understanding inequalities in class. I spend 10 minutes watching a video and I find it easy. You saved me from failing

    5th problem Fraction. Would -3/4 + 1/4= -2/4

    @rachelkuz
    We'l start by adding 1/2 to both sides.
    4x - 1/2 + 1/2 = 270 + 1/2
    4x = 270 1/2
    Since we're working with the fraction, we'll convert the mixed number into an improper fraction.
    4x = 541/2
    Then, we want to get the x by itself. Since it's multiplication we'll divide by 4 on both sides. However, we're working with fractions so I'll take a shortcut and multiply by 1/4, which is the same as dividing by 4.
    (1/4)(4x) = (541/2)(1/4)
    x = 541/8 = 67 5/8
    I hope that helps! :-)

    To solve that inequality, we'll start by subtracting 2.7g from both sides.
    2.7g - 2.7g + 12 > 3.2g - 2.7g
    12 > 0.5g
    Then divide by 0.5 on both sides to get the g by itself.
    12/0.5 > 0.5g/0.5
    24 > g or g < 24
    I hope that helps! Keep working hard on your math! :-)

    We'll start by subtracting 3 from both sides.
    (-5/6)x + 3 - 3 less than (LT) 1/2 - 3
    (-5/6)x LT -2 1/2
    (-5/6)x LT -5/2
    Then we'll multiply by the reciprocal to clear out the fraction that's left being multiplied by the x. Also, don't forget to flip the inequality symbol because we're multiplying by a negative on both sides.
    (-6/5)(-5/6)x LT (-5/2)(-6/5)
    x greater than (GT) 30/10
    x GT 3
    I hope that helps! Keeping working hard on your math! You can do it! :-)

    What part is giving you trouble? Perhaps you might start by looking at solving inequalities by adding or subtracting first?

  • @MartyBrandl
    @MartyBrandl  12 років тому

    Perhaps you could check out some of the videos that lead up to this one with one-step inequalities?
    Is there a certain type of problem that's giving you trouble? Let me know and I'll see if I can help! :-)

    hey, I was watching your video and I noticed that you made a mistake on #5. You simplified your problem until you got 2/4(c)-1/4 ≤ -3/4 after which you added 1/4 to each side. However, you forgot to write the negative -2/4 (you left it as 2/4(c) ≤ 2/4,). After multiplying by the reciprocal, you should've gotten an answer of "c ≤ -1" instead of "c ≤ 1".
    Besides that, amazing video, helped me a lot!
    Thanks! :)

    when adding/subtracting variables or like terms, do you always have to use the smallest value?

  • @MartyBrandl
    @MartyBrandl  12 років тому

    What part is giving you trouble? I'll see if I can explain it another way. :-)

    How do you mean "use the smallest value"? Can you give me an example?

    Hi. Thank you for this invaluable help. I am
    new to this math and having difficulty with it.
    Could you help me?
    4x-1/2=270. If you could explain this to me, I
    think I will come to understand it. Thank you!
