that on February 10, 20 people have the flu and that each day
the number of people (past and present) who have gotten
the flu triples. Let f(t) be the number of people (past and
present) who have gotten the flu by the day that is t days since
February 10.

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
