\frac{60}{x} - \frac{80}{x + 2} = 9

x = \frac{- 19 + 1441}{9}, x = - \frac{19 + 1441}{9}

Decimal Notation

x = 2.10672 \dots, x = - 6.32894 \dots

Solution steps

\frac{60}{x} - \frac{80}{x + 2} = 9

Multiply by LCM

60 (x + 2) - 80 x = 9 x (x + 2)

Solve

60 (x + 2) - 80 x = 9 x (x + 2) : x = \frac{- 19 + 1441}{9}, x = - \frac{19 + 1441}{9}

x = \frac{- 19 + 1441}{9}, x = - \frac{19 + 1441}{9}

Verify Solutions

Find undefined (singularity) points:

x = 0, x = - 2

Combine undefined points with solutions:

x = \frac{- 19 + 1441}{9}, x = - \frac{19 + 1441}{9}

y, x = \frac{5 y + 1}{y}

- \frac{7}{4 - 6 m} = 11

2 - \frac{6}{x ^{4}} = 0

16 = a^{- 2}

\frac{2}{y} + \frac{6}{y} = 4
