Question 4 unsaved (05.02 lc) 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? (5 points) question 4 options: 1) multiply the second equation by −4 to get −16x − 4y = −80 2) multiply the second equation by −1 to get −4x − y = −20 3) multiply the first equation by 2 to get 4x + 8y = 28 4) multiply the first equation by −1 to get −2x − 4y = −14
