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)

multiply the second equation by βˆ’4 to get βˆ’16x βˆ’ 4y = βˆ’80
multiply the second equation by βˆ’1 to get βˆ’4x βˆ’ y = βˆ’20
multiply the first equation by 2 to get 4x + 8y = 28
multiply the first equation by βˆ’1 to get βˆ’2x βˆ’ 4y = βˆ’14
