    X liters of 10% + (30 - x) liters of 22% = 30 liters of 15%

    Plugging in the numbers

    x (10) + (30 - x) 22 = 30 (15)

    Distribute

    10x + 660 - 22x = 450

    Combine like terms

    -12x = - 210

    Divide both sides by - 12

    x = 17.5

    30 - x = 12.5

    17.5 liters of 10% + 12.5 liters of 22% = 30 liters of 15%
