x-3y=-4..........................(1)

4x-5y=-23......................(2)

From (1) above:

x =-4 +3y sub this for x in (2) above

4(-4 + 3y) - 5y = -23

-16 + 12y -5y = -23

7y =-23 + 16

7y = - 7

y = -7/7

y = - 1 sub this into (1) above

x - (3* -1) =-4

x - (-3) =-4

x + 3 = -4

x =-4 - 3

x = -7
