Hello from MrBillDoesMath!

Answer:

a = 2.7

Discussion:

(2/3) ( 6a + 9 )  = 16.8         => the Distributive law

(2/3) (6a) + (2/3)9 = 16.8    =>

4a              + 6         = 16.8   => subtract 6 from both sides

4a                             = 16.8 -6 = 10.8     (divide both sides by 4)

a  = 10.8/4

   = 2.7

Thank you,

MrB
