Answer:
D
Step-by-step explanation:
Since we already know what -y is we can use that to find y.
y = -5x -21.
Let's substitute that in the bottom equation
-4x -5x - 21 = 6.
Simplify.
-9x = 27.
x = -3
Let's solve using
y = -5x -21.
to find y.
y = -5(-3) - 21
y = 15 - 21
y = -6.
There you have it!
x = -3, y = -6
So.. The correct answer choice is D
