Answer:

2/3 = x

Explanation:

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

First, solve the brackets.

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

Combine like terms.

-3x - 14 = 12x - 24

Add 3x to both sides.

-14 = 12x + 3x - 24

-14 = 15x - 24

Add 24 to both sides.

-14 + 24 = 15x

10 = 15x

Divide both sides by 15.

10/15 = x

To simplify the answer divide numerator and denominator by 5.

2/3 = x
