let's the certain number be x
the sum of a certain number and 16: x%2B16
equal to five times the number:5x

if the sum of a certain number and 16 is equal to five times the number, we know that
x%2B16=5x.....solve or x
16=5x-x
16=4x
x=16%2F4
x=4
so, the number is 4

check:
x%2B16=5x
4%2B16=5%2A4
20=20-> this confirms our solution
