W=\left(3S-20\right)\times 150
Subtract 350 from 500 to get 150.
W=450S-3000
Use the distributive property to multiply 3S-20 by 150.
450S-3000=W
Swap sides so that all variable terms are on the left hand side.
450S=W+3000
Add 3000 to both sides.
\frac{450S}{450}=\frac{W+3000}{450}
Divide both sides by 450.
S=\frac{W+3000}{450}
Dividing by 450 undoes the multiplication by 450.
S=\frac{W}{450}+\frac{20}{3}
Divide W+3000 by 450.
W=\left(3S-20\right)\times 150
Subtract 350 from 500 to get 150.
W=450S-3000
Use the distributive property to multiply 3S-20 by 150.
