Math Help! Please help me solve this perimeter problem!?

A rectangular painting is 4 inches longer than its width. If you add a 3-inch frame around the painting, the area increases by 48 square inches. What are the dimensions of the painting without the frame and with the frame?
Update: Yea I saw that the person forgot to add an extra 3 inches, I got the same answer that you did, meaning that it was impossible, but I just wanted to make sure that I wasn't going crazy. So thanks!
