8d-12=4d+8-2d+10
Use the distributive property to multiply 4 by d+2.
8d-12=2d+8+10
Combine 4d and -2d to get 2d.
8d-12=2d+18
Add 8 and 10 to get 18.
8d-12-2d=18
Subtract 2d from both sides.
6d-12=18
Combine 8d and -2d to get 6d.
6d=18+12
Add 12 to both sides.
6d=30
Add 18 and 12 to get 30.
d=\frac{30}{6}
Divide both sides by 6.
d=5
Divide 30 by 6 to get 5.
