x + y = 4(1 + y) + y = 4 1 + 2y = 4 1 - 1 + 2y = 4 2y = 4 y = 2
-x = -1 + y-x = -1 +2
-x = 1
.... that's as far I can go... sorry
Hey there!
Graphing can be tricky, but I’m happy to help!
The slope is -2 with a Y intercept of -4.
I included my graph from the equation to give you a visual of what it will look like.
Just let me know if you need further assistance or have more questions!

<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
