    x = 50

    Step-by-step explanation:

    Pieces of gum given by Sophia = x

    Pieces of gum left with Sophia after giving x pieces = 25 - x

    Pieces of gum given by Maria = 2 * Gums given by Sophia = 2x

    Pieces of gum left with Maria after giving 2x pieces = 75 - 2x

    Pieces of gum left with Sophia = Pieces of gum left with Maria

    25 - x = 75 - 2x

    2x - x = 75 - 25

    x = 50

    Pieces of gum left with Sophia is 50.
