8r(2s-4)=

Solution for 8r(2s-4)= equation:

Simplifying
8r(2s + -4) = 0

Reorder the terms:
8r(-4 + 2s) = 0
(-4 * 8r + 2s * 8r) = 0
(-32r + 16rs) = 0

Solving
-32r + 16rs = 0

Solving for variable 'r'.

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

Factor out the Greatest Common Factor (GCF), '16r'.
16r(-2 + s) = 0

Ignore the factor 16.
Subproblem 1
Set the factor 'r' equal to zero and attempt to solve:

Simplifying
r = 0

Solving
r = 0

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

Simplifying
r = 0
Subproblem 2
Set the factor '(-2 + s)' equal to zero and attempt to solve:

Simplifying
-2 + s = 0

Solving
-2 + s = 0

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

Add '2' to each side of the equation.
-2 + 2 + s = 0 + 2

Combine like terms: -2 + 2 = 0
0 + s = 0 + 2
s = 0 + 2

Combine like terms: 0 + 2 = 2
s = 2

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

Combine like terms: s + -1s = 0
0 = 2 + -1s

Simplifying
0 = 2 + -1s
