First multiply the 2 with the stuff in the first set of parentheses:

8a+10

then add the other stuff

8a +10+3a+3=68

combine like items

11a +13 = 68

subtract 13 from each side

11a = 55

divide each side by 11

a = 5

ok ill help you on this if you need it.
2(4a+5)+3a+3=68.
distribute the 2 into the parentheses, or-- multiply 2 times everything inside the parentheses. 2 x 4a= 8a. 2x5 =10.
8a+10+3a+3=68.
COLLECT TERMS.
8a+3a=11a
10+3=13
so, 11a+13=68
subtract 13 from each side so the variable (a) will only be on the left side.
11a+13=68
-13 -13
11a=55
divide both sides by 11 so you will get 'a' by itself.
11a=55
--- ---
11 11
a=5.

yayyy! (:
