Yes, many helpers here do know how to solve this problem. However on this forum we do not supply students with answer, after all this is a help forum. We actually prefer the student to solve their own problem with hints from forum helpers.

Since you have been trying to solve this for hours you must have some work to show us. After seeing your work then we will know what type of help you need.
