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

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

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

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

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

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

Reorder the terms:
2 + m + 1m = y

Combine like terms: m + 1m = 2m
2 + 2m = y

Solving
2 + 2m = 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 + 2m = -2 + y

Combine like terms: 2 + -2 = 0
0 + 2m = -2 + y
2m = -2 + y

Divide each side by '2'.
m = -1 + 0.5y

Simplifying
m = -1 + 0.5y
