8=-4/v

Solution

8 = - \frac{4}{v}

v = - \frac{1}{2}

Decimal Notation

v = - 0.5

Solution steps

8 = - \frac{4}{v}

Multiply both sides by

v

8 v = - 4

Divide both sides by

8

v = - \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

v = 0

Combine undefined points with solutions:

v = - \frac{1}{2}

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

\frac{1}{4.75} = \frac{6}{x}

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

5 - \frac{4}{x + 2} = \frac{4}{x - 1}

\frac{1}{x} + \frac{5}{x - 7} = 0
