-\frac{5}{2}+c=-2
Swap sides so that all variable terms are on the left hand side.
c=-2+\frac{5}{2}
Add \frac{5}{2} to both sides.
c=-\frac{4}{2}+\frac{5}{2}
Convert -2 to fraction -\frac{4}{2}.
c=\frac{-4+5}{2}
Since -\frac{4}{2} and \frac{5}{2} have the same denominator, add them by adding their numerators.
c=\frac{1}{2}
Add -4 and 5 to get 1.
