Hello!
Let's start by assigning our variable with a letter. I prefer n, but you can choose any letter (except the letter o).
Taking the problem step by step, we have:
12 times the number = 12n
20 less than 12 times the number = 12n - 20
Now, we equate the statement to 64:
12n - 20 = 64
12n = 64 + 20
12n = 84
¹²ⁿ⁄₁₂ = ⁸⁴⁄₁₂
n = 7
Therefore, we have our answer as 7.
If you want to verify, you can multiply 7 by 12 (which is 84) and subtract 20 (which will give you 64).
Hope this helped! x
