4-(6+(m-4))=y

Solution for 4-(6+(m-4))=y equation:

Simplifying
4 + -1(6 + (m + -4)) = y

Reorder the terms:
4 + -1(6 + (-4 + m)) = y

Remove parenthesis around (-4 + m)
4 + -1(6 + -4 + m) = y

Combine like terms: 6 + -4 = 2
4 + -1(2 + m) = y
4 + (2 * -1 + m * -1) = y
4 + (-2 + -1m) = y

Combine like terms: 4 + -2 = 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.
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
