We can simplify this expression:

 

6ab - ba + 3ab + a

                                         ba  =  ab    , so we can write...

 

6ab - ab + 3ab + a

                                         6 apples - 1 apple + 3 apples  =  8 apples     So...

                                         6ab - 1ab + 3ab  =  8ab

8ab + a
