Both original equations. So we will strategically multiply both equations by a constant to get the opposites. The difference in price between twice Peyton's order and Carter's order must be the price of 3 bagels, since otherwise the orders are the same! None of the coefficients are opposites. Here is what it would look like. The system does not have a solution. The equations are inconsistent and so their graphs would be parallel lines. Enter your equations separated by a comma in the box, and press Calculate! We will extend the Addition Property of Equality to say that when you add equal quantities to both sides of an equation, the results are equal. How much is one can of formula?
