Simplifying
7(v + -1) = 5v + 5 + -4(-5v + -1)

Reorder the terms:
7(-1 + v) = 5v + 5 + -4(-5v + -1)
(-1 * 7 + v * 7) = 5v + 5 + -4(-5v + -1)
(-7 + 7v) = 5v + 5 + -4(-5v + -1)

Reorder the terms:
-7 + 7v = 5v + 5 + -4(-1 + -5v)
-7 + 7v = 5v + 5 + (-1 * -4 + -5v * -4)
-7 + 7v = 5v + 5 + (4 + 20v)

Reorder the terms:
-7 + 7v = 5 + 4 + 5v + 20v

Combine like terms: 5 + 4 = 9
