To solve this system of equations, we can use the method of substitution.
Let's solve the second equation for x:
x = -3 - y
Now substitute this value into the first equation:
-9(-3 - y) - 6y = 9
27 + 9y - 6y = 9
3y = 9 - 27
3y = -18
y = -6
Now substitute this value back into the second equation to find x:
x + (-6) = -3
x - 6 = -3
x = -3 + 6
x = 3
Therefore, the solution to the system of equations is x = 3 and y = -6.
–9x − 6y = 9
x + y = –3
