Answer:
no solution
Explanation:
So first, you want to have one of the variables able to cancel out when you add the equations together.
To do this, divide the second equation by two
2x+2y=4
divide by 2
x+y=2
Next, get the variables on the same side on the both equations, so the second thing you do is add x to both sides on the top equation
y=-x+3
+x +x
y+x=3
Now you times one of them by -1 so a variable will cancle out.
y+x=3
x+y=2
*-1
y+x=3
-x-y=-2
Since all the variables cancel out, there is no solution
