It simplifies to #-10x+3#

Explanation:

Do the distributive multiplication first. Each number outside the bracket will multiply both terms in the bracket:
#(-3)(2x)+(-3)(1) - (2/3)(6x)+(2/3)(9)#

Where you will notice that the final term is written #+(2/3)(9)# because we are subtracting a negative term that was previously in the bracket (but no longer is).

The is the most difficult part to do correctly!

Now, just multiply each product:

#(-6x) + (-3)-(2*6x)/3+(2*9)/3#

#-6x-3-4x+6#

#-10x+3#
