2rs-9r+2s-7rs+11r-2s=

Solution for 2rs-9r+2s-7rs+11r-2s= equation:

Simplifying
2rs + -9r + 2s + -7rs + 11r + -2s = 0

Reorder the terms:
-9r + 11r + 2rs + -7rs + 2s + -2s = 0

Combine like terms: -9r + 11r = 2r
2r + 2rs + -7rs + 2s + -2s = 0

Combine like terms: 2rs + -7rs = -5rs
2r + -5rs + 2s + -2s = 0

Combine like terms: 2s + -2s = 0
2r + -5rs + 0 = 0
2r + -5rs = 0

Solving
2r + -5rs = 0

Solving for variable 'r'.

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

r(2 + -5s) = 0

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 + -5s)' equal to zero and attempt to solve:

Simplifying
2 + -5s = 0

Solving
2 + -5s = 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 + -5s = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -5s = 0 + -2
-5s = 0 + -2

Combine like terms: 0 + -2 = -2
-5s = -2

Add '5s' to each side of the equation.
-5s + 5s = -2 + 5s

Combine like terms: -5s + 5s = 0
0 = -2 + 5s

Simplifying
0 = -2 + 5s
