Ive been stuck on this problem for 11minutes now. :-( i Just need to know what X and Y equal. And if you could show me How you do it so ill understand for another problem like this i might run into. Thank you So much, Keith.Answer by stanbon(60774)   (Show Source): You can put this solution on YOUR website!-2x - 3y = -3 and 4x + 5y = 3 --------------------- Multiply thru the 1st equation by 5. Multiply thru the 2nd equation by -3. ---------------------------- -10x -15y = -15 -12x -15y = -9 --------------- Subtract the 2nd equation from the 1st to solve for "x": 2x = -6 x = -3 ------------ Substitute that into one of the original equations to solve for "y": -2*-3 -3y = -3 Divide thru by -3 to get: -2 +y = 1 y = 3 ============== Cheers, Stan H.
