Linear Solver app
The Linear Solver app enables you to solve a set of linear
equations. The set can contain two or three linear
equations.
In a two-equation set, each equation must be in the form
. In a three-equation set, each equation must
be in the form .
You provide values for a, b, and k (and c in three-equation
sets) for each equation, and the app will attempt to solve
for x and y (and z in three-equation sets).
The HP Prime will alert you if no solution can be found, or
if there is an infinite number of solutions.
Getting started with the Linear Solver app
The following example defines the following set of
equations and then solves for the unknown variables:
