How do you solve 3a a plus 1 - 4 a-5?

Answer 1

It is not possible to answer the question because the browser which you were required to use for posting the question strips out most mathematical symbols. It is therefore often impossible to be clear what the question was meant to be.

All that is visible here is 3 or 4 disjointed expressions: no equation in sight so there is nothing which can be solved.
