Question

-2x + 4(4 + x) = 2x - 4(6 - 3x)

Answer 1

1. -2x+4(4+x)

Like Terms : (-2x+x)(4+4)

-(1)x+8

2. 2x - 4(6-3x)

Like terms: (2x-3x)(6-4)

-(1)x+2

The answer shows that the problems are not equal to each other.

Answer 2

Expand both sides to get

$-2x + 16 + 4x = 2x - 24 + 18x$

Bring all terms involving the unkown on the left and all constant terms on the right:

$-2x + 4x -2x - 18x= - 24 -16$

Simplify both sides summing like terms:

$- 18x= -40$

Divide both sides by -18 to get

$x= \frac{-40}{-18} = \frac{20}{9}$
