    Linear Algebra help

    How would you give a direct proof of:

    If an integer has the form 6j -5, then it also has the form 3k+1, where j and k are integers.


    Sorry for the misspell on Algebra..ha!

    I am taking a linear algebra and matrix theory course. It the first course that I have taken that deals with abract alegbra.

    I figured that I put up the question in this area since it has to do with the course I am taking.
