636\pi +3\alpha =\pi
Multiply both sides of the equation by 3.
3\alpha =\pi -636\pi
Subtract 636\pi from both sides.
3\alpha =-635\pi
Combine \pi and -636\pi to get -635\pi .
\frac{3\alpha }{3}=-\frac{635\pi }{3}
Divide both sides by 3.
\alpha =-\frac{635\pi }{3}
Dividing by 3 undoes the multiplication by 3.
