-2 + -1m = Y

Solving
-2 + -1m = Y

Solving for variable 'm'.

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

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

Combine like terms: -2 + 2 = 0
0 + -1m = 2 + Y
-1m = 2 + Y

Divide each side by '-1'.
m = -2 + -1Y

Simplifying
m = -2 + -1Y
