drwls, is this correct,math
drawls this is from the previous post is this correct. solve the system by subtraction. 5x-3y=13 4x-3y=11 equation#2 woudl be 4x-3y=11 -3y = -4x+11 y = (4)/(3) x - (11)/(3) so now i substitute it to equation #1 5x - 3((4)/(3)x - (11)/(3)= 13 5x - 4 x +11 = 13 1x + 11 = 13 1x =...
