Question

3/5(15d+20)-1/6(18d-12)=38

Answer 1

3/5(15d+20)−1/6(18d−12)=38

Simplify

3/5(15d+20)−1/6(18d−12)=38

(3/5)(15d)+(3/5)(20)+−3d+2=38(Distribute)

9d+12+−3d+2=38

(9d+−3d)+(12+2)=38(Combine Like Terms)

6d+14=38

Subtract 14 from both sides.

6d+14−14=38−14

6d=24

Divide both sides by 6.

6d/6 = 24/6

d=4
