Solution for v+7-2(-4v-3)=5(v-1) equation:


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

Reorder the terms:
v + 7 + -2(-3 + -4v) = 5(v + -1)
v + 7 + (-3 * -2 + -4v * -2) = 5(v + -1)
v + 7 + (6 + 8v) = 5(v + -1)

Reorder the terms:
7 + 6 + v + 8v = 5(v + -1)

Combine like terms: 7 + 6 = 13
13 + v + 8v = 5(v + -1)

Combine like terms: v + 8v = 9v
13 + 9v = 5(v + -1)

Reorder the terms:
13 + 9v = 5(-1 + v)
13 + 9v = (-1 * 5 + v * 5)
13 + 9v = (-5 + 5v)

Solving
13 + 9v = -5 + 5v

Solving for variable 'v'.

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

Add '-5v' to each side of the equation.
13 + 9v + -5v = -5 + 5v + -5v

Combine like terms: 9v + -5v = 4v
13 + 4v = -5 + 5v + -5v

Combine like terms: 5v + -5v = 0
13 + 4v = -5 + 0
13 + 4v = -5

Add '-13' to each side of the equation.
13 + -13 + 4v = -5 + -13

Combine like terms: 13 + -13 = 0
0 + 4v = -5 + -13
4v = -5 + -13

Combine like terms: -5 + -13 = -18
4v = -18
