2x=\pi -\frac{\pi }{4}
Subtract \frac{\pi }{4} from both sides.
2x=\frac{3}{4}\pi
Combine \pi and -\frac{\pi }{4} to get \frac{3}{4}\pi .
2x=\frac{3\pi }{4}
The equation is in standard form.
\frac{2x}{2}=\frac{3\pi }{2\times 4}
Divide both sides by 2.
x=\frac{3\pi }{2\times 4}
Dividing by 2 undoes the multiplication by 2.
x=\frac{3\pi }{8}
Divide \frac{3\pi }{4} by 2.
