Simplifying
12(v + 1) + -4v = 4(2v + 3) + -21

Reorder the terms:
12(1 + v) + -4v = 4(2v + 3) + -21
(1 * 12 + v * 12) + -4v = 4(2v + 3) + -21
(12 + 12v) + -4v = 4(2v + 3) + -21

Combine like terms: 12v + -4v = 8v
12 + 8v = 4(2v + 3) + -21

Reorder the terms:
12 + 8v = 4(3 + 2v) + -21
12 + 8v = (3 * 4 + 2v * 4) + -21
12 + 8v = (12 + 8v) + -21
