2x+y=5 -------- eq 1 3x+2y=4 -------- eq2 now, multiply eq1 with -2 -2(2x+y=5) == -4x-2y=-10-----------eq 3   Add eq2 and eq3, (3x+2x)+(-4x-2y)= 4+(10) 3x+2y - 4x-2y = -6 Cancel +2y and -2y we get, 3x-4x=-6 -x=-6  therefore, x=6 Substitute value of x in eq1, 2x+y=52(6) + y=52(6) + y=512+y=5 y=5-12=-7  x=6 and y=-7y
