a=8
Explanation:
First make the denominators whole numbers.
22
 /3 + 6
/3 + 6
 /27
/27
Now make the denominators the same. To change 3 to 27, multiply by 9.
198
 /27 + 6
/27 + 6
 /27
/27
simplify6 
 which is 6
 which is 6 

 simplified to 6 x 3
 simplified to 6 x 3
 =18
=18

(198
 +18
+18
 )/27
)/27
198 plus 18 is 216
216
 /27
/27
216 divided by 27 is 8
8

8 is in the place of a in the equation a
 so a = 8
 so a = 8
