Math 8R - help!!!!!!!!!!!!!

posted by on .

Multi-Step Equations
Solving Equations with Variables on Both Sides

1) 5y + 4 = 4y + 5
11a + 9 = 4a + 30
2w + 3 = 4w - 5

2) 3a - 10 = 4 + a
2x - 1 = x - 3
6n + 4 = n - 11

3) 29r + 4 = 28 + 13r
7x - 11 = -19 + 3x

4) b + 3 = 2b - 7

I'm having a bit trouble and really confused with the problems. I'm NOT asking you to do this homework for me because that would wrong and I won't learn anything. Can you do #1, 2, 3, and 4 for me for I can do the problems below it since it's similar to them.

    1)
    5y + 4 = 4y + 5
    5y - 4y = 5 - 4
    y = 1

    2)
    3a - 10 = 4 + a
    3a - a = 4 + 10
    2a = 14
    a = 2

    3)
    29r + 4 = 28 + 13r
    29r - 13r = 28 - 4
    16r = 24
    r = 24/16 = 1 8/16 = 1 1/2
