```My problem is a problem with two non-linear equations, they are non-linear
with Exp. functions. My problem is that I can`t find any solution with

Solve[{(p2-380)Exp[p1-p2-20]/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)
+(p2-280)Exp[p1-p2-40]/((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])
^2) =(341-p1)/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)+
(1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])(p1-156.88)+
(p1-141)(Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])/
((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^2),
(p1-540)Exp[p1-p2-20]/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)+
(p1-140)Exp[p1-p2-40]/((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^
2) =(p2-184.12)(Exp[p1-p2-20]/(1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80]))
-(p2-181)((Exp[p1-p2-20])^2)/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)
+(p2-281)Exp[p1-p2-40](1+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])/
((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^2)}]

I would be very grateful if someone could tell me something how to progress
this problem.
