Best ResponseYou've already chosen the best response.0there are other ways to do it too i find this way the most easiest and to get x: you make your y value equal meaning, make you y value 10 to make the y value 10 you multiply the whole equation by 2 7x+5y=19 > 14x+10y=38 7x2y=16 (multiply 5 to get 10y)> 1410x = 80 dw:1325826985217:dw
