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