A demonstration file to show the basic ideas behind solving simultaneous equations by the method of elimination. Download file.

(a) Playing with various combinations of two equations, until one becomes easy to solve.

(b) Graphically demonstrating that the solutions stay the same under these operations.

Two files which assist students in learning the basic principles of "do the same to both sides" (DSBS) for solving equations in one variable. One file has the instructions; the second is a worksheet.

With TI-Interactive to help them avoid fatal calculation and algebraic errors, students can experiment with the basic DSBS moves, and get an overview of how to solve equations.

Download file. (When we have feedback on how the lesson can be improved, we will make the files attractive).
