Using a System of Equations to Find the Price of Apples and Oranges - In this video lesson regarding systems of equations, the following problem is worked: You've gone to a fruit stand to get some fresh produce. You notice that the person in front of you gets 5 apples and 4 oranges for 10 dollars. You get 5 apples and 5 oranges for 11 dollars. Can we solve for the price of an apple and an orange using this information in a system of linear equations in two variables? If yes, what is the solution? If no, what is the reason we cannot?
