Answer:

x = -8

y = 7

Step-by-step explanation:

To solve the system of equations, we need to substitute x = -8 on the second equation, so we get:

6x + 9y = 15

6(-8) + 9y = 15

Now, we can solve the equation for y, so:

-48 + 9y = 15

-48 + 9y + 48 = 15 + 48

9y = 63

9y/9 = 63/9

y = 7

So, the solution of the system is x = -8 and y = 7.
