#a=-9/7#

We can distribute the #3# to both terms in the parenthesis to get:

#6+color(blue)(3+9a)=2a#

NOTE: What I have in blue is the product of our distribution.

We can further simplify the left side of the equation to get:

#9+9a=2a#

We can subtract #9a# from both sides of the equation to get:

#9=-7a#

We can divide both sides by #-7# to get:

#a=-9/7#
