- 1`We are going to solve simultaneous equations.
- 2`We open the &Equations& window write the problem.
- 3`To create a new line we use the &Insert& button.
- 3`#The mouse is pointing at it.
- 4`After formulating the problem we press &ENTER&.
- 5`We evaluate the variable "$x$" from the first equation.
- 6`#We now substitute the value for "$x$" into the second equation.
- 7`We press &ENTER& to check the solution.
- 8`We transform the second equation.
- 9`#We notice that the second equation is a contradiction
- 9`#and we press the &Contradiction& button.
- 9`#The mouse is pointing at the button.
-
- 101`#We show how to use 2xy.
- 101``#"The presentation proceeds automatically."
- 101``#To move yellow panels use the mouse.
- 101`#Press ENTER on the KEYBOARD to continue.
-
- 102`#In a moment the &Examples& window will appear.
- 102`You can watch the same presentation again, or
- 102`#load the next example, or
- 102`#close the window and solve your own problem.
