 Question 222215: 1/2x+ (-1/2)y=1/2 (-1/3)x+(-3/4)y=2 I divided everything by 1/2 and you get x-y=1 for the first equation. the second equation i times everything by 12 and get (-4)x + (-9)y = 24 multiply the first equation by -9, so we get -9x +9y = -9. (-9)x + (9)y = -9 (-4)x + (-9)y = 24 I get (-15/13, -28/13) But it is wrong, what did i do wrong? Thanks for the help! Click here to see answer by stanbon(57984)
