4/6 = 2/x

Solution

\frac{4}{6} = \frac{2}{x}

x = 3

Solution steps

\frac{4}{6} = \frac{2}{x}

Cross multiply

4 x = 12

Divide both sides by

4

x = 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 3

\frac{100}{x} = 2

\frac{1}{x - 3} + 4 = \frac{21}{x - 3}

\frac{5.232}{x} = 20.5

\frac{x + 12}{x - 4} = 2

\frac{2 x}{x - 1} = 10
