20=5\left(6-s\right)
Multiply 10 and 2 to get 20.
20=30-5s
Use the distributive property to multiply 5 by 6-s.
30-5s=20
Swap sides so that all variable terms are on the left hand side.
-5s=20-30
Subtract 30 from both sides.
-5s=-10
Subtract 30 from 20 to get -10.
s=\frac{-10}{-5}
Divide both sides by -5.
s=2
Divide -10 by -5 to get 2.
