## anonymous one year ago in the square root of y minus the square root of 7 equals the square root of y+7, what is y?

1. marihelenh

Is this what it looks like? $\sqrt{y}-\sqrt{7}=\sqrt{y+7}$

2. marihelenh

If it is, you would square both sides to get rid of the square roots. Then you could solve for y.

Did you get a solution?

I just needed to know whether the solution contained any roots

You need to solve it to find out.
