Is this not the correct solution? For the order of operations you do parenthesis, exponents, multiple & divide, then addition & substraction. Multiplication and divide, as well as addition and subtraction are read from left to right. With that in mind here is how it is solved.
2+1 = 3 (inside the parenthesis so we do that first)
We then read left to right since we have multiplication and division.
6/2 = 3. 3*3 = 9.

The only other possible solution would be factoring in the 2 first, so it would be 2x1 + 2x3 = 6 and then do 6/6 which equals 1, but would the 2 before the parenthesis be associated with the parenthesis? I would assume it would be the equivalent of multiplying 2 x the equation inside the parenthesis.
