Abby wants to make a gallon of punch. she uses 2 quarts of orange juice, 1 cup of lemon juice, and 2 1/2 pints of pineapple juice. how many cups of water should she add to make 1 gallon?

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
