2 + 5 + 5v + 20y = 7(v + -1)

Combine like terms: 2 + 5 = 7
7 + 5v + 20y = 7(v + -1)

Reorder the terms:
7 + 5v + 20y = 7(-1 + v)
7 + 5v + 20y = (-1 * 7 + v * 7)
7 + 5v + 20y = (-7 + 7v)

Solving
7 + 5v + 20y = -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.
7 + 5v + -7v + 20y = -7 + 7v + -7v

Combine like terms: 5v + -7v = -2v
7 + -2v + 20y = -7 + 7v + -7v

Combine like terms: 7v + -7v = 0
7 + -2v + 20y = -7 + 0
7 + -2v + 20y = -7

Add '-7' to each side of the equation.
7 + -2v + -7 + 20y = -7 + -7

Reorder the terms:
7 + -7 + -2v + 20y = -7 + -7

Combine like terms: 7 + -7 = 0
0 + -2v + 20y = -7 + -7
-2v + 20y = -7 + -7
