Answer:
-5x - 8y = -5
Step-by-step explanation:
Whenever we two equations, we are essentially just adding the left sides up and then the right sides up. Here, let's write these into one whole big equation:
(4x - 4y) + (-9x - 4y) = -2 + (-3)
Taking the parentheses out, we have:
4x - 4y - 9x - 4y = -2 - 3
Combine like terms:
4x - 9x - 4y - 4y = -5
-5x - 8y = -5
