1.6x=2\pi
Swap sides so that all variable terms are on the left hand side.
\frac{1.6x}{1.6}=\frac{2\pi }{1.6}
Divide both sides of the equation by 1.6, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{2\pi }{1.6}
Dividing by 1.6 undoes the multiplication by 1.6.
x=\frac{5\pi }{4}
Divide 2\pi by 1.6 by multiplying 2\pi by the reciprocal of 1.6.
