    We are already given the equation to solve:

    x + 3x + 5 = 21

    The constant can be transposed to the other side

    x + 3x = 21 - 5

    The variables can be combined

    4x = 21 - 5

    The constants combine,

    4x = 16

    Dividing the whole equation with 4

    4x/4 = 16/4

    Cancelling out terms

    x = 4

    Therefore, the answer is

    A. 4 bicycles
