Solution for -5(-5-3v)-7(v+7)=-v+7v equation:


Simplifying
-5(-5 + -3v) + -7(v + 7) = -1v + 7v
(-5 * -5 + -3v * -5) + -7(v + 7) = -1v + 7v
(25 + 15v) + -7(v + 7) = -1v + 7v

Reorder the terms:
25 + 15v + -7(7 + v) = -1v + 7v
25 + 15v + (7 * -7 + v * -7) = -1v + 7v
25 + 15v + (-49 + -7v) = -1v + 7v

Reorder the terms:
25 + -49 + 15v + -7v = -1v + 7v

Combine like terms: 25 + -49 = -24
-24 + 15v + -7v = -1v + 7v

Combine like terms: 15v + -7v = 8v
-24 + 8v = -1v + 7v

Combine like terms: -1v + 7v = 6v
-24 + 8v = 6v
