1/(2b)+1/b =2

\frac{1}{2 b} + \frac{1}{b} = 2

b = \frac{3}{4}

Solution steps

\frac{1}{2 b} + \frac{1}{b} = 2

Multiply by LCM

3 = 4 b

Switch sides

4 b = 3

Divide both sides by

4

b = \frac{3}{4}

Verify Solutions

Find undefined (singularity) points:

b = 0

Combine undefined points with solutions:

b = \frac{3}{4}

\frac{8 ^{- 1}}{4 ^{- 1}} - a^{- 1} = 1

\frac{( 2 x - 3 ) ( x + 5 )}{x - 7} = 0

\frac{x + 2}{x} = \frac{3}{5}

4 + \frac{6}{x} = \frac{5}{2}

\frac{5}{x} + 3 = \frac{4}{x - 1}
