P=2+2W
Use the distributive property to multiply 2 by 1+W.
2+2W=P
Swap sides so that all variable terms are on the left hand side.
2W=P-2
Subtract 2 from both sides.
\frac{2W}{2}=\frac{P-2}{2}
Divide both sides by 2.
W=\frac{P-2}{2}
Dividing by 2 undoes the multiplication by 2.
W=\frac{P}{2}-1
Divide P-2 by 2.
P=2+2W
Use the distributive property to multiply 2 by 1+W.
