to solve the simple equation

[contro opinion]

there is a simple equation,
50/((1+x)**0.9389)+50/((1+x)**1.9389)+1050/((1+x)**2.9389)-1045=0
i input :
>>> from sympy import *
>>> x=Symbol('x')
>>>solve(50/((1+x)**0.9389)+50/((1+x)**1.9389)+1050/((1+x)**2.9389)-1045, x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    result = tsolve(f, *symbols)

 tsolve(50/((1+x)**0.9389)+50/((1+x)**1.9389)+1050/((1+x)**2.9389)-1045, x)

1.how can i solve it  with sympy?
2.how can i solve it  with other package?
