0.5Q=P-3
Swap sides so that all variable terms are on the left hand side.
\frac{0.5Q}{0.5}=\frac{P-3}{0.5}
Multiply both sides by 2.
Q=\frac{P-3}{0.5}
Dividing by 0.5 undoes the multiplication by 0.5.
Q=2P-6
Divide P-3 by 0.5 by multiplying P-3 by the reciprocal of 0.5.
P=0.5Q+3
Add 3 to both sides.
