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


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

Reorder the terms:
2v + 7 + -2(-1 + -5v) = 3(v + -1)
2v + 7 + (-1 * -2 + -5v * -2) = 3(v + -1)
2v + 7 + (2 + 10v) = 3(v + -1)

Reorder the terms:
7 + 2 + 2v + 10v = 3(v + -1)

Combine like terms: 7 + 2 = 9
9 + 2v + 10v = 3(v + -1)

Combine like terms: 2v + 10v = 12v
9 + 12v = 3(v + -1)

Reorder the terms:
9 + 12v = 3(-1 + v)
9 + 12v = (-1 * 3 + v * 3)
9 + 12v = (-3 + 3v)

Solving
9 + 12v = -3 + 3v

Solving for variable 'v'.

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

Add '-3v' to each side of the equation.
9 + 12v + -3v = -3 + 3v + -3v

Combine like terms: 12v + -3v = 9v
9 + 9v = -3 + 3v + -3v

Combine like terms: 3v + -3v = 0
9 + 9v = -3 + 0
9 + 9v = -3

Add '-9' to each side of the equation.
9 + -9 + 9v = -3 + -9

Combine like terms: 9 + -9 = 0
0 + 9v = -3 + -9
9v = -3 + -9

Combine like terms: -3 + -9 = -12
9v = -12

Divide each side by '9'.
v = -1.333333333
