M-[2-(2-m)]=

Solution for M-[2-(2-m)]= equation:

Simplifying
M + -1[2 + -1(2 + -1m)] = 0
M + -1[2 + (2 * -1 + -1m * -1)] = 0
M + -1[2 + (-2 + 1m)] = 0

Combine like terms: 2 + -2 = 0
M + -1[0 + 1m] = 0
M + -1[1m] = 0

Remove brackets around [1m]
M + -1 * 1m = 0

Multiply -1 * 1
M + -1m = 0

Solving
M + -1m = 0

Solving for variable 'M'.

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

Add 'm' to each side of the equation.
M + -1m + m = 0 + m

Combine like terms: -1m + m = 0
M + 0 = 0 + m
M = 0 + m
Remove the zero:
M = m

Simplifying
M = m
