The answer is 22.
Step-by-step explanation:
1) Replace the x with 17, and the y with 12.
2) 2(17) - 12
3) 2x17 = 34
4) 34 - 12 = 22
For any equation,

assume solution of a form, 
Which leads to,

Simplify to,

Then find solutions,

For non repeated real root y, we have a form of,

Following up,
For two non repeated complex roots
where,

and,
the general solution has a form of,

Or in this case,

Now we just refine and get,

Hope this helps.
