x+\frac{\pi }{2}=5\times 2
Multiply both sides by 2.
2x+\pi =10\times 2
Multiply both sides of the equation by 2.
2x+\pi =20
Multiply 10 and 2 to get 20.
2x=20-\pi
Subtract \pi from both sides.
\frac{2x}{2}=\frac{20-\pi }{2}
Divide both sides by 2.
x=\frac{20-\pi }{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{\pi }{2}+10
Divide 20-\pi by 2.
