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


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

Reorder the terms:
v + 7 + -2(-2 + -7v) = 7(v + -1)
v + 7 + (-2 * -2 + -7v * -2) = 7(v + -1)
v + 7 + (4 + 14v) = 7(v + -1)

Reorder the terms:
7 + 4 + v + 14v = 7(v + -1)

Combine like terms: 7 + 4 = 11
11 + v + 14v = 7(v + -1)

Combine like terms: v + 14v = 15v
11 + 15v = 7(v + -1)

Reorder the terms:
11 + 15v = 7(-1 + v)
11 + 15v = (-1 * 7 + v * 7)
11 + 15v = (-7 + 7v)

Solving
11 + 15v = -7 + 7v

Solving for variable 'v'.

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

Add '-7v' to each side of the equation.
11 + 15v + -7v = -7 + 7v + -7v

Combine like terms: 15v + -7v = 8v
11 + 8v = -7 + 7v + -7v

Combine like terms: 7v + -7v = 0
11 + 8v = -7 + 0
11 + 8v = -7

Add '-11' to each side of the equation.
11 + -11 + 8v = -7 + -11

Combine like terms: 11 + -11 = 0
0 + 8v = -7 + -11
8v = -7 + -11

Combine like terms: -7 + -11 = -18
8v = -18

Divide each side by '8'.
v = -2.25

Simplifying
v = -2.25
