System of equations on HP Prime

[DrD]

I think the Advanced Graphing app handles inequalities nicely. A couple of things to notice though:

1. Separate implicit multiplications: y ≤ 3x+1 should be: Y ≤ 3*X+1, etc.
2. Using the apps requires UPPER case variables!
y ≤ 3x+1 ==> Y ≤ 3*X+1

Enter your equations with those two changes into the Advanced Graphing app [Symb] page, and then use the [Plot] page to view your results.
