1. [CAS]
solve({(70/(23000+z)) = (x*177.35+(1-x)*1.133), ((23000+z)*(x*2571.11+(1-x)*696.21)) = (2412930.+z*2779.65)}, [x,z]);

2. [HOME]
CAS.solve("{(70/(23000+z)) = (x*177.35+(1-x)*1.133),((23000+z)*(x*2571.11+(1-x)*696.21)) = (2412930.+z*2779.65)},[x,z]")

3. [HOME] (Solve App):
[Symb]
E1: (70/(23000+Z))=X*177.35+(1-X)*1.133
E2: (23000+Z)*(X*2571.11+(1-X)*696.21)=23000*104.91+Z*2779.65
[Num]
Press [Solve] softkey

I typed the exact same thing you showed on way 1 (it was not a syntax error, just a solution error). I didn't try using the solve app, gonna try sometime.
