Algebra Custom App
The Custom App for Algebra focuses on solving linear systems of equations.
A description and help topics for this tool is given below.
Solving Linear Systems
Determines the solution to a user-defined system of linear equations
in 2, 3, or 4 variables.
- Specify the number of variables/equations.
The default is a two-variable/two-equation system. If you want to solve a
three- or four-variable system, make the appropriate choice from the Number
of Variables menu.
- Enter the coefficients and constant terms.
In the provided cells, enter the values of the coefficients and constant
terms. Be sure to include a negative sign where needed.
- Solve the system.
Choose Tool | Solve to find the solution (if a solution exists) in exact
and numeric forms. Alternatively, click the corresponding button ().
- Display the system graphically.
Choose the button
to view plots of the specified system of linear equations in two or three
variables. (This functionality is disabled for four-variable systems.)
