3 (2b-a) - (2b-a) First distribute the 3
(6b - 3a) - (2b-a) then I distributed the negative in the 2nd part
6b - 3a - 2b + a= then added/subtracted like terms
4b - 2a the answer

I'm sorry, I guess I don't know what you're asking. Did my answer to your question not help (see link)?
What do you mean by "when the letter is in the number"?
3 (2b - a) = 3*2b - 3*a = 6b - 3a
- (2b - a) = -1*2b - -1*a = -2b + a
Did this help you any?

first as you said, distribute
3(2b - a) - (2b - a)
6b - 3a -2b + a
once you've done that, combine the like terms.
6b - 2b - 3a + a
4b - 2a
you can even go a step farther and once again factor out the 2
2(2b - a)

3(2b-a) - (2b-a)
6b-3a -2b +a
4b-2a
the answer is 4b-2a
it's okay if the answer has 2 variables in it. since it is only an expression, you only need to simplify the expression, not solve for the variables. the answer is as simplified as possible.
