m + m + 4 + (8 + 2m) = 60

Reorder the terms:
4 + 8 + m + m + 2m = 60

Combine like terms: 4 + 8 = 12
12 + m + m + 2m = 60

Combine like terms: m + m = 2m
12 + 2m + 2m = 60

Combine like terms: 2m + 2m = 4m
12 + 4m = 60

Solving
12 + 4m = 60

Solving for variable 'm'.

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

Add '-12' to each side of the equation.
12 + -12 + 4m = 60 + -12

Combine like terms: 12 + -12 = 0
0 + 4m = 60 + -12
4m = 60 + -12

Combine like terms: 60 + -12 = 48
4m = 48

Divide each side by '4'.
m = 12

Simplifying
m = 12
