eliminate command

[omer]

Dear Community,
Is there any command corresponding to eliminate command of XCAS in HP Prime.

Eliminating one or more variables from a list of equations
The eliminate command eliminates variables from a list of equations.
• eliminate takes two arguments:
– eqns, a list of equations.
– vars, the variable or list of variables to eliminate. The equations can be given as expressions,
in which case they will be assumed to be 0.
• eliminate(eqns, vars) returns the equations with the variables vars eliminated or an indication
that Xcas cannot eliminate them.
Examples
Assuming the variables used haven’t been set to any values:
> eliminate([x=v0*t,y=y0-g*t^2], t)
> eliminate([x+y+z+t-2,x*y*t=1,x^2+t^2=z^2],[x,z])

eliminate in Xcas is based on an efficient Groebner basis engine that can handle double reverse lexicographic ordering (by double I mean order first with respect to the variables to be eliminated then with respect to other variables). I optimized this Groebner code several years for 64 bit processors. And unfortunately it fails on the arm 32 bits processor of the Prime, I made a check and it crashes on the Prime G1 (at least)/ I do not have an emulator where I could try to fix that efficiently (the hp "emulator" is not a real emulator, it is a simulator, it is using code compiled for amd64/x64 not for arm). This is sad, but running code calling Groebner basis code on a calculator is not recommended anyway because it would require large amount of RAM even for simple inputs...
