i begin with a number. I multiply it by 5, add 13 then subtract 22. what number did I begin with?
What is the number you got in the end?
You have missing information.
Lol
Let a be the number you started with
multiply by 5 ----- 5a
add 13 ----- 5a + 13
subtract 22 ----- 5a + 13 - 22 = 5a - 9
You end with 5a - 9 and you start with a. LOL.
