4+P=\frac{1}{2}
Swap sides so that all variable terms are on the left hand side.
P=\frac{1}{2}-4
Subtract 4 from both sides.
P=\frac{1}{2}-\frac{8}{2}
Convert 4 to fraction \frac{8}{2}.
P=\frac{1-8}{2}
Since \frac{1}{2} and \frac{8}{2} have the same denominator, subtract them by subtracting their numerators.
P=-\frac{7}{2}
Subtract 8 from 1 to get -7.
