Work Step by Step

You need to isolate the variable c. To do this you're going to add the $\frac{4}{7}$ to both sides of the equation. This will cancel out the -$\frac{4}{7}$ on the side with the c and isolate the variable. You're also going to balance the equation by adding $\frac{4}{7}$ to the other side with the $\frac{6}{7}$, giving us $\frac{10}{7}$ on the other side and resulting in our answer of c.
