What steps will reproduce the problem?

Given this equation Solve[((x-8.5)^2)+(y+9.5)^2==1.4,x] in online
symja. not able to get solution. 

but this equation Solve[((x-8.5556577)^2)+(y+9.551234)^2==14/10,x] gives the 
solution.

After equal == symbol, if i put decimal number, symja not giving solution. if i 
converted into faction.. it gives the solution..

Like that  this equation Solve[((x-8.5)^2/2.1)+(y+9.5)^2==14/10,x]  not giving 
the solution.. Instead of 2.1 if i give 21/10, the output is produced

denominator comes with deciamal number not working in solve
Solve[((x-8.5)^2/(2.1*x))+(y+9.5)^2==11/10,x] this is not working 
but Solve[((x-8.5)^2/((21/10)*x))+(y+9.5)^2==11/10,x] this is working
