-3=\frac{8\left(-7\right)}{7}+C
Express \frac{8}{7}\left(-7\right) as a single fraction.
-3=\frac{-56}{7}+C
Multiply 8 and -7 to get -56.
-3=-8+C
Divide -56 by 7 to get -8.
-8+C=-3
Swap sides so that all variable terms are on the left hand side.
C=-3+8
Add 8 to both sides.
C=5
Add -3 and 8 to get 5.
