    I am having troubles with time shifting and scaling of signals, concerning the order of operations.

    In this example the scale is done first, then inversion and finally shifting. But I have seen it done differently.

    For example if I had this:

    and I wanted to do something like x(-2t+5)

    What should I do first? or Could it be done different ways?

    EDIT: This is what I did:
