x can be 10 and y can be 2: 10 - 2 = 8
x can be 6 and y can be 5: 6 + 5 = 11
We could mix it up also and do the question x - y = 8 + x + y = 11.
Which it would go like this:
x can be 10 and y can be 2: 10 - 2 = 8
Now 8 is three away from 11.
x can be 2 and y can be 1: 2 + 1 = 3
8 + 2 + 1 = 11
Now lets finish our problem by simplifying it all:
8 + 3 = 11
I Hope That Helped :)
