2/x =8

Solution

\frac{2}{x} = 8

x = \frac{1}{4}

Solution steps

\frac{2}{x} = 8

Multiply both sides by

x

2 = 8 x

Switch sides

8 x = 2

Divide both sides by

8

x = \frac{1}{4}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{4}

\frac{r + 4.6}{r - 2.3} = 3.3

\frac{7}{k - 2} = \frac{5}{8}

\frac{x - 2}{x} = \frac{3}{5}

\frac{24}{s} = \frac{4}{12}

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