    Answer:

    40 grams of 13% alcohol solution and 10 grams of 18% alcohol solution.

    Step-by-step explanation:

    13%(x) + 18%(50-x) = 14%*50g   Multiply them all

    0.13x + (9-0.18x) = 7

    0.13x-0.18x + 9 = 7   Simplify the equation and subtract 0.13x from 0.18x

    9-0.05x = 7   Add 0.05x to each side

    9 = 7+0.05x   Subtract 7 from both sides

    0.05x = 2   Multiply each side by 100

    5x = 200   Divide both sides by 5

    x = 40

    50 – 40 = 10

    40 grams and 10 grams
