System of Linear Eaquations
1) Using what you know already how do you think we would find which x and y will solve these two equations at the same time? 3x + 4y = 13 -4x + 3y = 23 2) What would the solutions to this system of equations look like? 3) Solve 4x + 3y = 17 10x - 3y = 11 4) Play with the app changing the coffiecents and see if you end up with two equations which: a) has one solution b) has no solutions c) has infinite solutions
5) Write out in a paragraph what you discovered by playing with the app.
