$\left \{ {{x+y=\pi } \atop {Sinx+Siny=1}} \right.\\\\\left \{ {{x=\pi-y } \atop {Sin(\pi-y) +Siny=1}} \right.\\\\\left \{ {{x=\pi-y } \atop {Siny +Siny=1}} \right.\\\\\left \{ {{x=\pi-y } \atop {2Siny=1}} \right.\\\\\left \{ {{x=\pi-y } \atop {Siny=\frac{1}{2} }} \right.\\\\\left \{ {{x=\pi-y } \atop {\left[\begin{array}{ccc}y=\frac{\pi }{6}+2\pi k, k\in Z \\y=\frac{5\pi }{6}+2\pi k, k\in Z \end{array}\right }} \right.$

$\left[\begin{array}{ccc}\left \{ {{x=\pi-\frac{\pi }{6}-2\pi k,k \in Z} \atop {y=\frac{\pi }{6}+2\pi k,k \in Z}} \right. \\\left \{ {{x=\pi -\frac{5\pi }{6}-2\pi k,k \in Z} \atop {y=\frac{5\pi }{6}+2\pi k,k \in Z}} \right. \end{array}\right\\\\\\\left[\begin{array}{ccc}\left \{ {{x=\frac{5\pi }{6}-2\pi k,k \in Z} \atop {y=\frac{\pi }{6}+2\pi k,k \in Z}} \right. \\\left \{ {{x=\frac{\pi }{6}-2\pi k,k \in Z} \atop {y=\frac{5\pi }{6}+2\pi k,k \in Z}} \right. \end{array}\right$
