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