x-(42)/x =-1

x - \frac{42}{x} = - 1

x = 6, x = - 7

Solution steps

x - \frac{42}{x} = - 1

Multiply both sides by

x

x^{2} - 42 = - x

Solve

x^{2} - 42 = - x : x = 6, x = - 7

x = 6, x = - 7

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6, x = - 7

5.916 x = 1 - (\frac{1}{1 + x})^{10}

0 = 1 - \frac{1}{x - 2}

2 x - \frac{12}{2 - x} = 7 + \frac{11 x + 11}{9}

\frac{7}{x + 4} - \frac{1}{x} = \frac{8}{15}

\frac{2 x}{x - 2} - 2 = \frac{- 4}{2 - x}
