~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

I will assume that, by default, the designation    is used in its standard meaning 

as the ratio of the circle circumference to its diameter,   = 3.14159265...


Factor left side of the equation

     = 0.


Then EITHER   = 1,  which gives  2x = 0,  x = 0;

     OR       = 9,  which gives  2x =  = ,  

             x =  =  =  =  = 0.95971312  (rounded).    ANSWER
