Hey gang, this isn\'t actually any of my college coursework, but these are some problems from my son\'s 8th grade algebra homework that I can\'t seem to help him with. They are probably simple, but I don\'t have to take a math until next semester, so I am really at a 15 year loss. Here are a few more, please simplify: a -4 c 0 = (3x-2)/y = 7ab -2 /3w = x -5 y -7 = x -5 y 7 = Thanks again oracle!! Solution a -4 c 0 = 1/a 4 (3x-2)/y = (3x-2) y -1 7ab -2 /3w = 7a/3wb 2 x -5 y -7 = 1/x 5 y 7 x -5 y 7 = y 7 /x 5 .
