Answer:

x= 0, y = -1

Step-by-step explanation:

5x + 16y = -16

-9x – 8y = 8.     , multiply both sides of this equation by 2

 5x + 16y = -16

-18x – 16y = 16  , add both equations so the y will eliminate

----------------------------

-13x           = 0,  divide both sides by -13

    x = 0

5·0 + 16y = -16, substitute x= 0 in the first equation and solve for y

        16y = -16 , divide both sides by 16

          y = -1

The solution of the system of equation is the point ( x= 0, y = -1)
