6/4 = 3/x

Solution

\frac{6}{4} = \frac{3}{x}

x = 2

Solution steps

\frac{6}{4} = \frac{3}{x}

Cross multiply

6 x = 12

Divide both sides by

6

x = 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2

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

\frac{x + 7}{x + 3} = \frac{5}{x}

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

160 = \frac{180 ( n - 2 )}{n}

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