7/1, I think that’s right
The three ordered pair for the solution is
(0,5), (1,3), (2,1)
Yes, the decimal form of 
is indeed a repeating decimal. The expression is equivalent to 
, which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
When a=6,
2a - 3 = 2(6) - 3 = 12 - 3 = <em><u>9</u></em>
