Answer:
(-1, -2)
Step-by-step explanation:
-9x= 5 - 2y
15x = -11 + 2y => 2y = -11 - 15x
Plug the value for 2y into the first equation.
-9x = 5 - 15x - 11. Solve for x.
-9x = -6 - 15x.
-9x + 15x = -6.
6x = -6.
x = -1.
Now that we found x, we will solve for y.
2y = -11 - 15(-1)
2y = -11 + 15
2y = -4
y = -2.
Thus, our solution set is (-1, -2).
Hope this helps!
