    The equation is x/2+7=13

    She spent half her allowance on the movies and gained seven dollars for washing the car and she ended up with $13.

    Get x by itself by misusing 7 from each side.

    This gets you x/2=6.

    Then multiply 2 to both sides.

    This gets you x=12.

    Her weekly allowance is $12.
