9mn-m+m+m-n-n=

Solution for 9mn-m+m+m-n-n= equation:

Simplifying
9mn + -1m + m + m + -1n + -1n = 0

Reorder the terms:
-1m + m + m + 9mn + -1n + -1n = 0

Combine like terms: -1m + m = 0
0 + m + 9mn + -1n + -1n = 0
m + 9mn + -1n + -1n = 0

Combine like terms: -1n + -1n = -2n
m + 9mn + -2n = 0

Solving
m + 9mn + -2n = 0

Solving for variable 'm'.

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

Add '2n' to each side of the equation.
m + 9mn + -2n + 2n = 0 + 2n

Combine like terms: -2n + 2n = 0
m + 9mn + 0 = 0 + 2n
m + 9mn = 0 + 2n
Remove the zero:
m + 9mn = 2n

Combine like terms: 2n + -2n = 0
m + 9mn + -2n = 0
