A school needs to buy new notebook and desktop computers for its computer lab. The notebook computers cost $375 each, and the desktop computers cost $325 each. How many total computers would someone buy if they get 18 notebooks and 11 desktop computers? How many total computers would someone buy if they get N notebooks and D desktop computers?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
