Solve the system of equations and enter as order pairs.
Y=-x+5
Y=x-3
----------
Substitute for "y" and solve for "x"::
x-3 = -x+5
2x = 8
x = 4
-----
Solve for "y"::
y = x -3
y = 4-3
y = 1
------
Answer:: x = 4 ; y = 1

1. Rewrite both systems so that the x and y are on the same side of the equal sign and the numbers are on the other side:
-x - y = -5
x - y = 3
2. Add both systems together, since we can easily get rid of x:
-x - y + x - y = -5 + 3 ----->
-2y = -2
3. Divide both sides by -2, giving us our value of y:
y = -2 / -2 = 1
4. Replace the y in either original equation with 1. I'll use the second one:
1 = x - 3
x = 4
So, in ordered pair form, our answer is (4,1).
