$S o l v e f o r r e a l n u m b e r s$ $4 s i n \frac{π}{26} + 4 x s i n \frac{3 π}{26} + 4 s i n \frac{9 π}{26} = x + \sqrt{13}$

	$x (1 - 4 s i n \frac{3 π}{26}) = 4 (s i n \frac{9 π}{26} + s i n \frac{π}{26}) - \sqrt{13}$ $x = \frac{4 (s i n \frac{9 π}{26} + s i n \frac{π}{16}) - \sqrt{13}}{(1 - 4 s i n \frac{3 π}{26})}$
