Answer:
x= 0, y = -1
Step-by-step explanation:
5x + 16y = -16
-9x – 8y = 8. , multiply both sides of this equation by 2
-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)
(0,-1)
