You can put this solution on YOUR website!
If you can do one of these, you can do them all, so I'll do one, and you do the other two.
I'm presuming that you mean: sqrt%28x%2B9%29=4
:
Square both sides of the equation, yielding:
:
x%2B9=16
x=7
:
Checking our work:
:
sqrt%287%2B9%29=4
sqrt%2816%29+=+4, Check
