    3

    Step-by-step explanation:

    21x + 6 = 3x + 60 subtract 3x from both sides

    (21x-3x) + 6 = 60

    18x + 6 = 60 subtract 6 from both sides

    18x = 60-6

    18x = 54 divide by 18

    x = 3

    Answer: the number is 3

    Step-by-step explanation:

    This can be written mathematically as

    21y + 6 = 60 + 3y

    21y - 3y = 60 - 6

    18y = 54

    y = 54/18 = 3
