4= 1/x

Solution

4 = \frac{1}{x}

x = \frac{1}{4}

Decimal Notation

x = 0.25

Solution steps

4 = \frac{1}{x}

Multiply both sides by

x

4 x = 1

Divide both sides by

4

x = \frac{1}{4}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{4}

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

\frac{6}{7} = \frac{24}{n + 11}

\frac{x}{3} - \frac{9}{x} = 2

\frac{9}{x} + 2 = 20

\frac{8}{x} = \frac{x}{2}
