3/9 = 2/x

Solution

\frac{3}{9} = \frac{2}{x}

x = 6

Solution steps

\frac{3}{9} = \frac{2}{x}

Cross multiply

3 x = 18

Divide both sides by

3

x = 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6

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

\frac{x - 26}{x} = \frac{31}{100}

\frac{1}{z} - 2 \cdot z = 1

\frac{2}{c + 3} - 3 = \frac{7}{c + 3}

\frac{x + 1}{x - 8} = 10
