Dear all,

I recently met a problem when I was trying to do some calculations. The equation is "6.672221.95092Log[1 + 0.21977(p0.5/x)^(1/1.95092)] == 45.396021.01257Log[1 + 1.4128510^-4(p*0.5/(1 - x))^(1/1.01257)", I want to know when p is in the range from 0 to 100 the corresponding values of x. Following is what I have done in Mathematica:

In the export result, I met something strange:

Almost all x values are complex numbers. However, suppose I set the p equal to 100; the corresponding x value calculated from WolframAlpha is 0.9798.

I think it is related to the starting value, but I don't know how can I fix it.

Thank you very much.
