Question

4x+8 = 7x-7

2(4-x) - 12 = 36+ 2x

2/3x 7 = 3

I tried but I don’t get it… I knew how to do it but forgot please help

Answer 1

1) x = 5

2) x = -10

3) x = 15

Explanation:

4x + 8 = 7x - 7

8 = 3x - 7

3x = 15

x = 5

2(4 - x) - 12 = 36 + 2x

8 - 2x - 12 = 36 + 2x

-4 - 2x = 36 + 2x

-4 - 4x = 36

-4x = 40

x = -10

2/3x - 7 = 3

2/3x = 10

x = 10 * 3/2

x = 15
