 Question 359030: Solve the following system by the addition method. -18x+42y= -10 Y= 3/7xAnswer by stanbon(57424)   (Show Source): You can put this solution on YOUR website!Solve the following system by the addition method. -18x+42y= -10 Y= 3/7x ---- Rearrange the 2nd equation: 7y = 3x Then 3x - 7y = 0 ------- System: -18x + 42y = -10 3x - 7y = 0 ----- Multiply thru the lower equation by 6: ------ System: -18x + 42y = -10 18x - 42y = 0 ----- Adding you get: 0 = -10 ----- The system is inconsistent. There is no solution for the system. ============== Cheers, Stan H.
