 Question 466805: Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. -5x – 7y = 25.5 -2x + 10y = -9 Answer by stanbon(57347)   (Show Source): You can put this solution on YOUR website!Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. -5x – 7y = 25.5 -2x + 10y = -9 ----------- Multiply thru 1st equation by -2 Multiply thru 2nd equation by -5 ------- 10x + 14y = -51 10x - 50y = 45 ---- Subtract and solve for "y": 64y = -96 y = -3/2 ============== Solve for "x": 10x + 14y = -51 10x + 14(-3/2) = -51 10x - 21 = -51 10x = 30 x = 3 --------- Cheers, Stan H. ==========================
