| | Simultaneous Equation Solver HP 33s |
 | | I suggest Cramers rule for finding determinets and staying with only using 9 variables (actually 10, you should store the determinet as well, rather than trust the stack). |
 | | The HP-20S has a 99-line built-in Cramer's Rule solver for 3x3 linear systems, which can also be used for 2x2 systems. |
 | | Actually, I see now that the 11c has tow different programs--a cramers rule method ofr solving equations, as well as a matrix manipulation program. |
