2 = \frac{3}{7} - \frac{6}{b}

b = - \frac{42}{11}

Decimal Notation

b = - 3.81818 \dots

Solution steps

2 = \frac{3}{7} - \frac{6}{b}

Multiply by LCM

14 b = 3 b - 42

Move

3 b

to the left side

11 b = - 42

Divide both sides by

11

b = - \frac{42}{11}

Verify Solutions

Find undefined (singularity) points:

b = 0

Combine undefined points with solutions:

b = - \frac{42}{11}

x^{- 2} + x + 8 x = 5

(x) = - \frac{26}{x + 7}

\frac{24 - x}{x} = \frac{x}{36 - x}

2 + \frac{6}{y} = \frac{7}{5}

\frac{1}{( x + 1 ) ^{3}} = 0
