Work Step by Step
We start by distributing. We distribute -1 to both terms in the parenthesis on the right side of the equation. We have $3(2-c)=-(c+4)$ is $6-3c=-c-4$. Now, we want to isolate c with its coefficient. We can add $c$ and $-6$ to both sides to accomplish this. Now we have $-2c=-10$ which is $c=5$.
