Solution for 3(m+7)-12(m-12)=10m-8m equation:


Simplifying
3(m + 7) + -12(m + -12) = 10m + -8m

Reorder the terms:
3(7 + m) + -12(m + -12) = 10m + -8m
(7 * 3 + m * 3) + -12(m + -12) = 10m + -8m
(21 + 3m) + -12(m + -12) = 10m + -8m

Reorder the terms:
21 + 3m + -12(-12 + m) = 10m + -8m
21 + 3m + (-12 * -12 + m * -12) = 10m + -8m
21 + 3m + (144 + -12m) = 10m + -8m

Reorder the terms:
21 + 144 + 3m + -12m = 10m + -8m

Combine like terms: 21 + 144 = 165
165 + 3m + -12m = 10m + -8m

Combine like terms: 3m + -12m = -9m
165 + -9m = 10m + -8m
