Evaluate the expressions. x = 3, y=5 5x + 2y - 3x + 4y 2x + 6y 3x - 2y - 2x + 4y x + 2y 3y + 2x + 4y + y 2x + 8y 3y + 4y - 3x - 2x 7y - 5x 9x - 7x - 10y + 4y 2x - 6y What are some things (more than one!) that you notice about the matched up pairs. List all things you notice. Use what you notice from the matched up pairs to write this problems in a shorter version. 3x + 4y + 8x + 2y 7x + 10y 11x + 6y 17xy 5x + 2y Which math problem would you rather do?A.) 3x + 4y + 8x + 2y B.)11x + 6yWhy?
