Simplifying
9v + 3 + -2(-5v + -4) = 7(v + -1)

Reorder the terms:
9v + 3 + -2(-4 + -5v) = 7(v + -1)
9v + 3 + (-4 * -2 + -5v * -2) = 7(v + -1)
9v + 3 + (8 + 10v) = 7(v + -1)

Reorder the terms:
3 + 8 + 9v + 10v = 7(v + -1)

Combine like terms: 3 + 8 = 11
11 + 9v + 10v = 7(v + -1)

Combine like terms: 9v + 10v = 19v
11 + 19v = 7(v + -1)
