In the lab, Ahmad has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as Solution B. Solution A is 19% alcohol and Solution B is 15% alcohol. How many milliliters of Solution A does he use, if the resulting mixture has 159 milliliters of pure alcohol?

    so A = 2B and .19A + .15B = 159
