-0.25(4r-8)=0.5(4-2y)

Solution for -0.25(4r-8)=0.5(4-2y) equation:

Simplifying
-0.25(4r + -8) = 0.5(4 + -2y)

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

Add '-2' to each side of the equation.
2 + -2 + -1r = 2 + -2 + -1y

Combine like terms: 2 + -2 = 0
0 + -1r = 2 + -2 + -1y
-1r = 2 + -2 + -1y

Combine like terms: 2 + -2 = 0
-1r = 0 + -1y
-1r = -1y

Solving
-1r = -1y

Solving for variable 'r'.

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

Divide each side by '-1'.
r = y

Simplifying
r = y
