Answer 22

Simplifying
8x + 4(4x + -3) = 4(6x + 4) + -4

Reorder the terms:
8x + 4(-3 + 4x) = 4(6x + 4) + -4
8x + (-3 * 4 + 4x * 4) = 4(6x + 4) + -4
8x + (-12 + 16x) = 4(6x + 4) + -4

Reorder the terms:
-12 + 8x + 16x = 4(6x + 4) + -4

Combine like terms: 8x + 16x = 24x
-12 + 24x = 4(6x + 4) + -4

Reorder the terms:
-12 + 24x = 4(4 + 6x) + -4
-12 + 24x = (4 * 4 + 6x * 4) + -4
-12 + 24x = (16 + 24x) + -4

Reorder the terms:
-12 + 24x = 16 + -4 + 24x

Combine like terms: 16 + -4 = 12
-12 + 24x = 12 + 24x

Add '-24x' to each side of the equation.
-12 + 24x + -24x = 12 + 24x + -24x

Combine like terms: 24x + -24x = 0
-12 + 0 = 12 + 24x + -24x
-12 = 12 + 24x + -24x

Combine like terms: 24x + -24x = 0
-12 = 12 + 0
-12 = 12

Solving
-12 = 12
