What is the answer to x- y equals y if x equals 8?

Answer 1

For this problem, write it out... x-y=y... x=2y...8=2y...8/2=y...4=y

First, I made both y's on the same side( I added a y to both sides).

Then, I replaced the x with an 8.

Then, I divide out the 2 from both sides.

This leaves me with 4=y

So... x=8, y=4, 8-4=4
