3= 1/x

Solution

3 = \frac{1}{x}

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

3 = \frac{1}{x}

Multiply both sides by

x

3 x = 1

Divide both sides by

3

x = \frac{1}{3}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{3}

\frac{4 k - 10}{k} = 8

V = \frac{4 π ^{2} R ^{3}}{T ^{2}}

x, f = \frac{k}{x + 1} + 2

\frac{x ^{2}}{x + 160} = 80

\frac{3}{x} + \frac{4}{x + 1} = 2
