x = 4

Solution steps

\frac{1}{x} = \frac{1}{4}

Cross multiply

4 = x

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4

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

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

\frac{12}{x} = \frac{2}{18}

\frac{3}{x + 1} = \frac{1}{2}

7 x^{- 2} + 3 x - 10 = 0
