The x would equal 6 because if you substitue 6 for x and 2 for y, when you add them, it will be 8. Divide that by 2 and it will result in 4. And if you subtract 2 from 6, your answer will still be 4.
x+y/2 Substitute 6 for x and 2 for y 6+2/2 Add 6 and 2 8/2 Divide Final Answer: 4
6-2 Subtract Final Answer: 4
Since both of the answers result in 4, that is what makes x=6 and y=2 true.
