M+3n-2(m+3n)-(8-2n)=

Solution for M+3n-2(m+3n)-(8-2n)= equation:

Simplifying
M + 3n + -2(m + 3n) + -1(8 + -2n) = 0
M + 3n + (m * -2 + 3n * -2) + -1(8 + -2n) = 0
M + 3n + (-2m + -6n) + -1(8 + -2n) = 0
M + 3n + -2m + -6n + (8 * -1 + -2n * -1) = 0
M + 3n + -2m + -6n + (-8 + 2n) = 0

Reorder the terms:
-8 + M + -2m + 3n + -6n + 2n = 0

Combine like terms: 3n + -6n = -3n
-8 + M + -2m + -3n + 2n = 0

Combine like terms: -3n + 2n = -1n
-8 + M + -2m + -1n = 0

Solving
-8 + M + -2m + -1n = 0

Solving for variable 'M'.

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

Add '8' to each side of the equation.
-8 + M + -2m + 8 + -1n = 0 + 8

Reorder the terms:
-8 + 8 + M + -2m + -1n = 0 + 8

Combine like terms: -8 + 8 = 0
0 + M + -2m + -1n = 0 + 8
M + -2m + -1n = 0 + 8

Combine like terms: 0 + 8 = 8
M + -2m + -1n = 8

Add '2m' to each side of the equation.
M + -2m + 2m + -1n = 8 + 2m

Combine like terms: -2m + 2m = 0
M + 0 + -1n = 8 + 2m
M + -1n = 8 + 2m

Add 'n' to each side of the equation.
M + -1n + n = 8 + 2m + n

Combine like terms: -1n + n = 0
M + 0 = 8 + 2m + n
M = 8 + 2m + n

Simplifying
M = 8 + 2m + n
