4m-21+6m+6=0
Use the distributive property to multiply -3 by 7-2m.
10m-21+6=0
Combine 4m and 6m to get 10m.
10m-15=0
Add -21 and 6 to get -15.
10m=15
Add 15 to both sides. Anything plus zero gives itself.
m=\frac{15}{10}
Divide both sides by 10.
m=\frac{3}{2}
Reduce the fraction \frac{15}{10} to lowest terms by extracting and canceling out 5.
