**8 + y = 8 – y **

__What is the only value for y that makes this equation true?__

\(y=0\) is the answer

Let's look at the original equation:

\(8+y=8-y\)

To solve this, we must isolate y. This means that we need to get the equation into y equals form.

\(8+y=8-y\) Subtract 8 on both sides

If you subtract a number on one side of the equation, you must do that on the other, of course. When you subtract 8 on both sides, you are left with:

\(y=-y\) Add y to both sides

\(y+y=0\) Combine like terms

\(2y=0\) Divide by 2 to isolate y

\(y=0\)

If you are ever unsure whether an answer is correct or not, plug the value you got back in the original equation:

\(8+0=8-0\)

\(8=8\)

This statement is true, so y=0 is the correct and the only correct value for y.
