(2pi)/b =4pi

\frac{2 π}{b} = 4 π

b = \frac{1}{2}

Solution steps

\frac{2 π}{b} = 4 π

Multiply both sides by

b

2 π = 4 πb

Switch sides

4 πb = 2 π

Divide both sides by

4 π

b = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

b = 0

Combine undefined points with solutions:

b = \frac{1}{2}

x = \frac{13}{3 x - 1} - 3

876 = \frac{230}{v}

r, a = \frac{v ^{2}}{r}

\frac{12}{x} = \frac{3}{2}

24 - \frac{6}{y} = 3
