690.8=200\pi +2\pi h_{10}
Multiply 2 and 100 to get 200.
200\pi +2\pi h_{10}=690.8
Swap sides so that all variable terms are on the left hand side.
2\pi h_{10}=690.8-200\pi
Subtract 200\pi from both sides.
\frac{2\pi h_{10}}{2\pi }=\frac{690.8-200\pi }{2\pi }
Divide both sides by 2\pi .
h_{10}=\frac{690.8-200\pi }{2\pi }
Dividing by 2\pi undoes the multiplication by 2\pi .
h_{10}=\frac{1727}{5\pi }-100
Divide 690.8-200\pi by 2\pi .
