Re: Solve fails with this simple inequality problem

"Meter = " can't work there, since it gives Meter a numeric value, hence  
you can't use it as the Solve variable. Infinite recursion results.

If you mean == instead (much more likely with Solve), then:

Solve[Meter == Floor[Sqrt[19] + 7] && Meter < 6, Meter]

{}

There is no solution, since

Floor[Sqrt[19] + 7]

11

and

11 < 6

False

Using the built-in symbol Meter as a variable makes no sense, anyway.
