8= 4/x

Solution

8 = \frac{4}{x}

x = \frac{1}{2}

Decimal Notation

x = 0.5

Solution steps

8 = \frac{4}{x}

Multiply both sides by

x

8 x = 4

Divide both sides by

8

x = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{2}

\frac{3 x}{x + 3} = 8 - \frac{9}{x + 3}

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

\frac{1}{x} = - 1

x - 3 = \frac{10}{x}

\frac{1}{x ^{2}} + 4 x^{2} - 4 = 0
