Answer 2

You can use the substitution method.
Take the second equation and solve it for the value of y.
Then substitute that value in for y in the first equation so that you can solve it for x.
Once you know what x is, substitute the value of x into the second equation to find y.

4x + y = -33
y = -33 - 4x

9x + 5(-33 - 4x) = -132
9x - 165 - 20x = -132
-11x = 33
x = -3 <---

4(-3) + y = -33
-12 + y = -33
y = ?

Hope this helps! :)
