Solution for 7(v+1)-4(5-2v)=-5(v-9) equation:


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

Reorder the terms:
7(1 + v) + -4(5 + -2v) = -5(v + -9)
(1 * 7 + v * 7) + -4(5 + -2v) = -5(v + -9)
(7 + 7v) + -4(5 + -2v) = -5(v + -9)
7 + 7v + (5 * -4 + -2v * -4) = -5(v + -9)
7 + 7v + (-20 + 8v) = -5(v + -9)

Reorder the terms:
7 + -20 + 7v + 8v = -5(v + -9)

Combine like terms: 7 + -20 = -13
-13 + 7v + 8v = -5(v + -9)

Combine like terms: 7v + 8v = 15v
-13 + 15v = -5(v + -9)

Reorder the terms:
-13 + 15v = -5(-9 + v)
-13 + 15v = (-9 * -5 + v * -5)
-13 + 15v = (45 + -5v)
