 Question 41066: Solve the system by elimination. If the system is inconsistent or has dependent equations, say so. -7x + 5y = -20 -3x - 2y = 8 Answer by stanbon(57967)   (Show Source): You can put this solution on YOUR website!1st: -7x + 5y = -20 2nd: -3x - 2y = 8 To eliminate the y-terms do as follows: Multiply 1st thru by 2 to get: 1st: -14x+10y=-40 Multiply 2nd thru by 5 to get: 2nd: -15x-10y=40 Add these two equations to get: -29x=0 x=0 Substitute that value into original 1st or 2nd to solve for "y". -7(0)+5y=-20 y=-4 SOLUTION: x=0,y=4 Cheers, stan H.
