I have no idea how to solve your question, but even if you solve it,
the command solve will not work in this kind of problem. You should
use some command which solves numerically. Something like
this example: g(x)==5, where g=integral(exp(t)) and t from 0 to x
sage: find_root(lambda x:5-numerical_integral(exp(t),0,x)[0],1,2)
1.791759469228055
and we check it:
sage: numerical_integral(exp(t),0,_)[0]
5.0
