Simplifying

4x + - 8 = - 4(2x + - 3) + 4

Reorder the terms : - 8 + 4x = - 4(2x + - 3) + 4

Reorder the terms : - 8 + 4x = - 4( - 3 + 2x) + 4 - 8 + 4x = ( - 3 * - 4 + 2x * - 4) + 4 - 8 + 4x = (12 + - 8x) + 4

Reorder the terms : - 8 + 4x = 12 + 4 + - 8x

Combine like terms : 12 + 4 = 16 - 8 + 4x = 16 + - 8x

Solving - 8 + 4x = 16 + - 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8x' to each side of the equation.

- 8 + 4x + 8x = 16 + - 8x + 8x

Combine like terms : 4x + 8x = 12x - 8 + 12x = 16 + - 8x + 8x

Combine like terms : - 8x + 8x = 0 - 8 + 12x = 16 + 0 - 8 + 12x = 16

Add '8' to each side of the equation.

- 8 + 8 + 12x = 16 + 8

Combine like terms : - 8 + 8 = 0

0 + 12x = 16 + 8

12x = 16 + 8

Combine like terms : 16 + 8 = 24

12x = 24

Divide each side by '12'.

X = 2

Simplifying

x = 2.
