-7 + -3v + 11 + 12v = 3(4v + 5) + -4(v + 4)

Reorder the terms:
-7 + 11 + -3v + 12v = 3(4v + 5) + -4(v + 4)

Combine like terms: -7 + 11 = 4
4 + -3v + 12v = 3(4v + 5) + -4(v + 4)

Combine like terms: -3v + 12v = 9v
4 + 9v = 3(4v + 5) + -4(v + 4)

Reorder the terms:
4 + 9v = 3(5 + 4v) + -4(v + 4)
4 + 9v = (5 * 3 + 4v * 3) + -4(v + 4)
4 + 9v = (15 + 12v) + -4(v + 4)

Reorder the terms:
4 + 9v = 15 + 12v + -4(4 + v)
4 + 9v = 15 + 12v + (4 * -4 + v * -4)
4 + 9v = 15 + 12v + (-16 + -4v)

Reorder the terms:
4 + 9v = 15 + -16 + 12v + -4v

Combine like terms: 15 + -16 = -1
4 + 9v = -1 + 12v + -4v

Combine like terms: 12v + -4v = 8v
4 + 9v = -1 + 8v

Solving
4 + 9v = -1 + 8v

Solving for variable 'v'.
