I can help!!!
Step-by-step explanation:
Answer:
x=3, y=-1
Step-by-step explanation:
x+y = 2
x -y =4
I will use elimination to eliminate the variable y. Add the two equations together.
x+y = 2
x -y =4
-------------
2x = 6
Divide each side by 2
2x/2 = 6/2
x = 3
But we still don't know y
x+y =2
Substitute x=3 into the equation
3+y =2
Subtract 3 from each side
3-3 +y =2-3
y =-1
