Укажите все ответы уравнения \(2+4\cos\left(\frac{\pi}{4}-x\right)=0\)

\(\frac{11\pi}{12}+2\pi{n}; n\in{Z}\)
\(-\frac{5\pi}{12}+2\pi{n}; n\in{Z}\)
\(\frac{3\pi}{4}+2\pi{n}; n\in{Z}\)
\(-\frac{11\pi}{12}+2\pi{n}; n\in{Z}\)
\(\frac{5\pi}{12}+2\pi{n}; n\in{Z}\)
\(\frac{2\pi}{3}+2\pi{n}; n\in{Z}\)
\(-\frac{2\pi}{3}+2\pi{n}; n\in{Z}\)
\(\frac{\pi}{12}+2\pi{n}; n\in{Z}\)
\(\frac{7\pi}{12}+2\pi{n}; n\in{Z}\)
\(\frac{\pi}{2}+\pi{n}; n\in{Z}\)
\(\frac{13\pi}{12}+2\pi{n}; n\in{Z}\)
