I don't know what to do with the problem 7x + y = 7. I need to find what x is when y is 7. Can anyone help me? -test7004

Try to get the y isolated first by adding or subtracting elements on either side of the equals side. In this case, start by subtracting 7x from the left side, leaving you with y = 7x + 7. Now you can punch it into your calculator and it will give you the answer. The answer in this case for y=7 is x=0. Alternatively, you could guess and check. -Dilts
