102=2(m+3m)
We move all terms to the left:
102-(2(m+3m))=0
We add all the numbers together, and all the variables
-(2(+4m))+102=0
We calculate terms in parentheses: -(2(+4m)), so:We move all terms containing m to the left, all other terms to the right
2(+4m)
We multiply parentheses
8m
Back to the equation:
-(8m)
-8m=-102
m=-102/-8
m=12+3/4
