Answer: c=4
Step-by-step explanation:
- Add 15 on each side to get rid of the -15 on the left side.
- That results in getting: -5c=-20. That would be the answer for what -5c equals.
- To find what c equals, we must divide by -5 on each side. Thus, c=4.
- If we plug it in, it works, so we know the answer is correct.
