Combine like terms: 9 + -6 = 3
6 + -1(3 + -1m + 2m) = y

Combine like terms: -1m + 2m = 1m
6 + -1(3 + 1m) = y
6 + (3 * -1 + 1m * -1) = y
6 + (-3 + -1m) = y

Combine like terms: 6 + -3 = 3
3 + -1m = y

Solving
3 + -1m = y

Solving for variable 'm'.

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

Add '-3' to each side of the equation.
3 + -3 + -1m = -3 + y

Combine like terms: 3 + -3 = 0
0 + -1m = -3 + y
-1m = -3 + y

Divide each side by '-1'.
m = 3 + -1y

Simplifying
m = 3 + -1y
