i need help with this problem:2x-y=-4

Question

-x-y=5
when you answer this question can you plz include the steps you did to get the final answer?

Answer 1

A way to solve this type of problem:
First express one of the variables in terms of the other.
-x-y = 5
or, y = -5-x
Now substitute that value for y into the other equation.
2x -(-5-x)=-4
Solve for x, then substitute the known x value into either equation to solve for y.

Answer 2

Subtract the second equation from the first.

3x = -9
x = -3

y = -x -5 = -2
