dux3000 Posted September 14, 2015 Share Posted September 14, 2015 3x + 2y = 52x + 3y = 8Quantity A: xQuantity B: ySolution: http://www.greenlighttestprep.com/module/gre-algebra-and-equation-solving/video/972I solved this by solving for x and y, which turns out to be the slow way. The solution is a lot faster but I don't think I'd ever come up with it on the test. Does anyone have any similar questions that test the same concept so I can practice?
