-0.25(4v-8)=0.5(4-20)

Solution for -0.25(4v-8)=0.5(4-20) equation:

Simplifying
-0.25(4v + -8) = 0.5(4 + -20)

Reorder the terms:
-0.25(-8 + 4v) = 0.5(4 + -20)
(-8 * -0.25 + 4v * -0.25) = 0.5(4 + -20)
(2 + -1v) = 0.5(4 + -20)

Combine like terms: 4 + -20 = -16
2 + -1v = 0.5(-16)

Multiply 0.5 * -16
2 + -1v = -8

Solving
2 + -1v = -8

Solving for variable 'v'.

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

Add '-2' to each side of the equation.
2 + -2 + -1v = -8 + -2

Combine like terms: 2 + -2 = 0
0 + -1v = -8 + -2
-1v = -8 + -2

Combine like terms: -8 + -2 = -10
-1v = -10

Divide each side by '-1'.
v = 10

Simplifying
v = 10
