Mystery Maths Week 2

I think of a number. I times it by 5 and I subtract 11. Finally I add on 100. My answer is 134. What was my original number?

    134-100=34
    34+11=45
    455=9

    Inverse:

    9×5=45
    45-11=34
    34+100=134

    The number 9 is hiding in Mr Baines classroom where the plugs are near his desk.
