RE: System of equations on HP Prime
My favorite way to solve linear systems is an efficient way on the keyboard: just a single division. The example below is the system you gave above. The screen capture on the left is with Textbook Display Mode turned on, and the one on the right is with it turned off, otherwise they are identical.

This nifty method works with any size system. Just be sure to use single square bracket for the numerator (which contains the constants from the right side of the equations) and double square brackets for the denominator (which contains the coefficients from the left side of the equations). If your Prime flashes a warning at you, saying something like "This shortcut is a Bad Thing which we included only under pressure from users of previous HP calculator models", ignore it. Big Grin
