18\left(2-d\right)=-5\times 2\left(d+2\right)
Multiply 6 and 3 to get 18.
36-18d=-5\times 2\left(d+2\right)
Use the distributive property to multiply 18 by 2-d.
36-18d=-10\left(d+2\right)
Multiply -5 and 2 to get -10.
36-18d=-10d-20
Use the distributive property to multiply -10 by d+2.
36-18d+10d=-20
Add 10d to both sides.
36-8d=-20
Combine -18d and 10d to get -8d.
-8d=-20-36
Subtract 36 from both sides.
-8d=-56
Subtract 36 from -20 to get -56.
d=\frac{-56}{-8}
Divide both sides by -8.
d=7
Divide -56 by -8 to get 7.
