    Alright, first let's make a variable for the number.

    'n'

    Pretty easy right?

    Now, we know that the equation contains the sum of n and 3.

    n + 3

    Since 35 is 9 more than the sum of n and 3:

    (n + 3) + 9 = 35

    Great! Now we have the equation!

    We can open the parentheses and add 9 and 3

    n + 12 = 35

    Subtract both sides by 12:

    n = 23

    The unknown number is 23!
