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 β4 to get β16x β 4y = β80
multiply the second equation by β1 to get β4x β y = β20
multiply the first equation by 2 to get 4x + 8y = 28
multiply the first equation by β1 to get β2x β 4y = β14
