Solving Simultaneous Equations
|
The two interactive tutorials in this document take the user step-by-step through the methods of solving linear systems of equations in two variables by both substitution and elimination methods. Have the systems randomly chosen, or enter your own, then follow the directions. Because this uses keyboard input, this document is not supported by the Player, but can be downloaded and run locally.
