\frac{1}{2}-b-\frac{4}{2}=0
Convert 2 to fraction \frac{4}{2}.
\frac{1-4}{2}-b=0
Since \frac{1}{2} and \frac{4}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{3}{2}-b=0
Subtract 4 from 1 to get -3.
-b=\frac{3}{2}
Add \frac{3}{2} to both sides. Anything plus zero gives itself.
b=-\frac{3}{2}
Multiply both sides by -1.
