3/x = 1/3

Solution

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

x = 9

Solution steps

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

Cross multiply

9 = x

Switch sides

x = 9

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 9

\frac{5}{x} - 2 = \frac{5}{4}

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

\frac{2}{7} = \frac{10}{t + 5}

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

3 x + \frac{54}{2 x + 3} = 18
