[br]Use the applet below for practice on the [color=#0000ff]Substitution Method[/color].

1. Create a problem by setting initial values for [color=#0000ff]a, b, c, m,[/color] and [color=#0000ff]n[/color] using the sliders. Set [color=#0000ff]"steps"[/color] to [color=#ff0000]0[/color].[br][br]2. On a separate sheet, solve the equations shown on the applet using the substitution method. Follow the working demo.[br][br]3. Confirm your answer by moving the slider marked [color=#0000ff]"steps." [/color]This will show you a step by step solution to the particular system of linear equations that you have created[color=#0000ff].[/color][br][br]4. If your answer is correct, create a new problem by changing the values of [color=#0000ff]a, b, c, m,[/color] and [color=#0000ff]n[/color] using the sliders. If your answer is wrong, rework the problem and correct your mistakes before creating a new problem.[br][br]Repeat as many times as needed until you master the concept.
