Question

Plz help figure out this problem
Also m has to be the exact same number
m+2m+7=m+11

Answer 1

m+2m+7=m+11
m+2m-m=11-7
         2m=4
            m=2

Answer 2

remember you can add m's together
1m+2m=3m
so we have
3m+7=m+11
subtract 1m frmo both sides
3m-1m+7=m-m+11
2m+7=0+11
subtract 7 from both sides
2m=11-7
2m=4
divid eobh tisdes by 2
2/2m=4/2
1m=4/2
m=2

m=2
