Solution for 15(v-1)+4(v+3)=2(7+v) equation:


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

Reorder the terms:
15(-1 + v) + 4(v + 3) = 2(7 + v)
(-1 * 15 + v * 15) + 4(v + 3) = 2(7 + v)
(-15 + 15v) + 4(v + 3) = 2(7 + v)

Reorder the terms:
-15 + 15v + 4(3 + v) = 2(7 + v)
-15 + 15v + (3 * 4 + v * 4) = 2(7 + v)
-15 + 15v + (12 + 4v) = 2(7 + v)

Reorder the terms:
-15 + 12 + 15v + 4v = 2(7 + v)

Combine like terms: -15 + 12 = -3
-3 + 15v + 4v = 2(7 + v)

Combine like terms: 15v + 4v = 19v
-3 + 19v = 2(7 + v)
-3 + 19v = (7 * 2 + v * 2)
-3 + 19v = (14 + 2v)

Solving
-3 + 19v = 14 + 2v

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.
