2/3 = 4/x

Solution

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

x = 6

Solution steps

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

Cross multiply

2 x = 12

Divide both sides by

2

x = 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6

\frac{27}{x} = \frac{51}{8}

x = \frac{15}{x - 2}

\frac{1}{x} - 2 - \frac{2}{x} - 3 = 5

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

\frac{4}{5 x} - 3 = 0
