When we write out the system of equations, we will get:
x+y=18
x-y=8
We can then use elimination to get just one variable.
x+y=18
+x-y= 8
Which gives us: 2x=26
We then divide by 2 and get: x=13
We next plug that into one of the two equations and solve for the other variable: (13)+y=18
We subtract 13 from both sides and get: y=5
So the two numbers are 13 and 5.
