Yeah answer C is right because from question, 5x -3y=1......eq 1 x-2y=-4 ......eq2 From equation 2 too we can write x = -4 + 2y ... put this x value on eq 1 so 5(-4+2y) - 3y = 1 -20 + 10y -3y=1 Or, 7y=21 So y=21/7=3 And put the value of y on equation 2 x -2 X 3 =-4 Or x= -4+6 So x=2 answer from question too we get value of x and y is 2,3 so xy= 2X3=6 answer
