You can put this solution on YOUR website! This can be set up using equal ratios:
7/6 = 30594/x
Cross multiply
7x = 30594*6
x = 30594*6/7 = 26223.43
Since you cannot have a partial vote, you can round to 26223.
...
Note that saying the ratio is 7/6 is very imprecise.
The concept of significant digits tells us that the number 7 to one significant digit means the value lies between 6.5 and 7.5. Likewise a value of 6 could be between 5.5 and 6.5. So a ratio of 7/6 could be as wide a range as 7.5/5.5. Clearly, 30594/26223 is within this range.

Since the incubent won by a 7:6 ratio, then the incubent had 7 parts of the total votes, while the opponent had 6 parts of the total votes. Now, since the opponent's 6 parts is represented by 30,594 votes, using I as the incubent's votes, we can say that:
6I = 7 * 30,594 --------- Cross-mutiplying
I = 35,693
Therefore, I, or the incubent won  votes.

Check
---------
To check, you just need to realize that there are 13 (7 + 6) total parts, and that the incubent received  of the 66,287 (30,594 + 35,693) votes that were cast between the two candidates, while the opponent received  of the 66,287 votes that were cast between the two candidates.
_____________________________ OR ______________________________________
we can just simply set the ratio as the incubent's votes to the opponent's votes, which is 35,693:30,594, or 7:6, or  , or  .
