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


Simplifying
7v + -7v = -4(v + -7) + 4(1 + -1v)

Combine like terms: 7v + -7v = 0
0 = -4(v + -7) + 4(1 + -1v)

Reorder the terms:
0 = -4(-7 + v) + 4(1 + -1v)
0 = (-7 * -4 + v * -4) + 4(1 + -1v)
0 = (28 + -4v) + 4(1 + -1v)
0 = 28 + -4v + (1 * 4 + -1v * 4)
0 = 28 + -4v + (4 + -4v)

Reorder the terms:
0 = 28 + 4 + -4v + -4v

Combine like terms: 28 + 4 = 32
0 = 32 + -4v + -4v

Combine like terms: -4v + -4v = -8v
0 = 32 + -8v

Solving
0 = 32 + -8v

Solving for variable 'v'.

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

Add '8v' to each side of the equation.
0 + 8v = 32 + -8v + 8v
Remove the zero:
8v = 32 + -8v + 8v

Combine like terms: -8v + 8v = 0
8v = 32 + 0
8v = 32

Divide each side by '8'.
v = 4

Simplifying
v = 4
