Answer by nerdybill(7090)   (Show Source): You can put this solution on YOUR website!4x-5y=38 7x-8y=22 . multiply top eq by 7; bottom eq by -4 then ADD: 28x-35y=266 -28x+32y=-88 ---------------- -3y = 178 y = 178/(-3) y = -178/3 y = -59.33 . find x by substituting above into: 4x-5y=38 4x-5(-59.33)=38 4x=-258.67 x = -64.67
