Heath wants 10l of a solution that is 90% bleach. he will combine pure bleach with a mixture that is 20% bleach. a.) write a system of equations to model the problem. use p for the number of liters of pure bleach and m for the number of liters of the mixture that is 20% bleach.
b.) solve the system. show work, . how many liters of pure bleach will heath use? how many liters of the 20% mixture will he use?

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
