 Question 635471: I have to solve the system of equationg 7x+5y=10 -2x+2y=4 Please help, thank you :)Answer by stanbon(57250)   (Show Source): You can put this solution on YOUR website!solve the system of equation: 7x+5y=10 -2x+2y=4 ------ Multiply thru 1st by 2. Multiply thru 2nd by 7. ------------------- 14x + 10y = 20 -14x + 14y = 28 -------------------- Add and solve for "y": 24y = 48 y = 2 ---- Solve for "x": 7x + 5y = 10 7x + 10 = 10 x = 0 ================ Cheers, Stan H. ================
