Remove parenthesis around (1 + -1m)
3 + -1(4 + 1 + -1m) = y

Combine like terms: 4 + 1 = 5
3 + -1(5 + -1m) = y
3 + (5 * -1 + -1m * -1) = y
3 + (-5 + 1m) = y

Combine like terms: 3 + -5 = -2
-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.
