Systems of equations practice problems

READ THIS BEFORE STARTING If there is a repeating decimal, just put the tenths place ONLY. Also, round your answers to the nearest HUNDREDTH if it doesn't repeat. Hope this helps. Credits to the many websites I used to create this; I also made some hard ones too. *NOTE: make sure to put x = or y = Enjoy, -The Creator (Also, one of them has no solution)
