Press the green flag. Two random equations will be generated. If you are looking to solve the system, then do so now. After you are done, hit space, and the computer will solve the system for you, using the elimination method. This isn't exactly the elimination method, but uses an algorithm derived from it.
The necessary fixes are the same as my System Solver/Grapher. ----------------------------------------------------------------------------- What is the elimination method? It seeks to eliminate one variable in a system: x + 2y = 4 2x - 2y = 5 Because 2x - 2y is the same thing as 5, adding 2x -2y to one side of the first equation while adding 5 to the other side will keep the equation balanced. Also, in the process, 2y and -2y will zero out, leaving a manageable equation with only one variable: 3x = 9 so x = 3. If x = 3, then x + 2y = 4 becomes 3 + 2y = 4, and y is 0.5, so the solution is (3, 0.5). In some cases, you have to multiply one or both equations by a number to make elimination possible: x + 2y = 10 x -y = 5 To make elimination possible, multiply both sides of the second equation by 2 to get: 2x - 2y = 10. Now, elimination is possible.
