x=53

radar · Answer

$$\sqrt{5x-9}=16$$
Square both sides
5x-19=256  Add 19 to both sides
5x=275        Divide both sides by 5
x=55

I do learn a lot from the posts, but again, I am not interested in the "answer" but the steps/procedures used to obtain the answer.  Curious minds need to know.

radar · Answer

I do learn from the posts, but as I said, only if the problem is worked out showing the procedures required to get the solution.  The answer is of no consequence.  Some do this quite well, satellite, and amistre to just name a couple.  You will note that they are often requested (by name) to solve problems.
