M-(M+3-2M-3)=Y

Solution for M-(M+3-2M-3)=Y equation:

Simplifying
M + -1(M + 3 + -2M + -3) = Y

Reorder the terms:
M + -1(3 + -3 + M + -2M) = Y

Combine like terms: 3 + -3 = 0
M + -1(0 + M + -2M) = Y
M + -1(M + -2M) = Y

Combine like terms: M + -2M = -1M
M + -1(-1M) = Y

Remove parenthesis around (-1M)
M + -1 * -1M = Y

Multiply -1 * -1
M + 1M = Y
