Question

Given: -7(x+2)+4x=6(2x-4); Prove x=2/3

Answer 1

see below

Explanation:

-7(x+2)+4x=6(2x-4)

Distribute

-7x -14 +4x = 12x -24

Combine like terms

-3x-14 = 12x-24

Add 3x to each side

-3x-14+3x = 12x-24+3x

-14 = 15x-24

Add 24 to each side

-14+24 = 15x -24+24

10 = 15x

Divide each side by 15

10/15 =15x/15

2/3 =x
