Answer:
x = -1, y = 4
Step-by-step explanation:
x + y = 3
-x + y = 5
This means that y = 3 - x
We can substitute this value into the equation
-x + y = 5
-x + 3 - x = 5
3 - 2x = 5
Subtract 3 from both sides
-2x = 2
Divide both sides by -2
x = -1
Plugging this number into the equation, we have:
-1 + y = 3
Add 1 to both sides
y = 4
