Answer:

16/7

Step-by-step explanation:

3     a - 2

-- = --------   can be reduced to:

7       6

1     a - 2

-- = --------  

7       2

and then cross-multiplication results in:

7(a - 2) = 2

We must isolate a - 2 first, and then a.  Dividing both sides of this equation by 7 results in:

a - 2 = 2/7

Adding 2 to both sides results in:

a = 2  2/7  or  a = 16/7
