30+8m+420-12m=370
Use the distributive property to multiply 12 by 35-m.
450+8m-12m=370
Add 30 and 420 to get 450.
450-4m=370
Combine 8m and -12m to get -4m.
-4m=370-450
Subtract 450 from both sides.
-4m=-80
Subtract 450 from 370 to get -80.
m=\frac{-80}{-4}
Divide both sides by -4.
m=20
Divide -80 by -4 to get 20.
