Question

If you add 5 to me and then divide by 9 you get 3 what number am I

Answer 1

So,

If you translate it into mathematical form, you get
$\frac{5 + x}{9} = 3$

First, you would multiply both sides by 9.
$5 + x = 27$

Subtract 5 from both sides
x = 22

Answer 2

The answer is 22. Work backwards and solve. Take 3 multiply by 9, subtract 5.
