Me ; -; amy mixes 12 liters of 16% acid solution with a 40% acid solution, which results in 32% acid solution. let x represent the number of liters of 40% solution used and let y represent the number of liters of mixture. which system of equations can be used to find the number of liters of 40% acid solution in the mixture? y = x + 12; 0.4y = 0.32x + 3.84 y = x + 12; 0.4y = 0.32x + 1.92 y = x + 12; 0.32y = 0.4x + 4.8 y = x + 12; 0.32y = 0.4x + 1.92
