I did, and just had a very hard time. Here are the issues I found:
1. you need to create all variables having a name other than A..Z manually using STO in home prior to entering equations otherwise the equation editor believes you entered multiplications. Also because of CAS, it seems that using lower case variables is not an option. Very cumbersome...
2. the solver demands that you have as many equations as variables. This may be right for linear equations but totally wrong in the vast majority of real life cases. I was trying psychometric equations for which 2 inputs suffice to achieve all other air conditions. 50g MES handles that smoothly.
3. in some occasions you may need macros. Here I need to export BASIC functions from Program to support this while the 50g will accepts RPL objects. While this is in reality conceptually identical, I find the RPL approach with objects in the same directory far more natural, and also RPL is more adapted to calculator than BASIC. Just a matter of opinion here...

Edit: I revisited my conclusion because this is not intended to be a flame against the Prime. I'm not an expert of the Prime and may be there are ways to achieve the same as the 50g but for now I haven't been able to.
