-1(1 + -1m + n) = 0
(1 * -1 + -1m * -1 + n * -1) = 0
(-1 + 1m + -1n) = 0

Solving
-1 + 1m + -1n = 0

Solving for variable 'm'.

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

Add '1' to each side of the equation.
-1 + 1m + 1 + -1n = 0 + 1

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

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

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

Add 'n' to each side of the equation.
1m + -1n + n = 1 + n

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

Divide each side by '1'.
m = 1 + n

Simplifying
m = 1 + n
