Step-by-step explanation:

Step-by-step explanation:

Simplifying

28 + 12x = 8x + -4

Reorder the terms:

28 + 12x = -4 + 8x

Solving

28 + 12x = -4 + 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.

28 + 12x + -8x = -4 + 8x + -8x

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

28 + 4x = -4 + 8x + -8x

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

28 + 4x = -4 + 0

28 + 4x = -4

Add '-28' to each side of the equation.

28 + -28 + 4x = -4 + -28

Combine like terms: 28 + -28 = 0

0 + 4x = -4 + -28

4x = -4 + -28

Combine like terms: -4 + -28 = -32

4x = -32

Divide each side by '4'.

x = -8

Simplifying

x = -8
