1. ## 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!

Hint: 6j - 5 = 6j - 6 + 1

what's this have to do with linear algebra?

3. sorry

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.
