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

x = \frac{1 + 13}{2}, x = \frac{1 - 13}{2}

Solution steps

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

Cross multiply

3 (x + 1) = (x + 2) x

Solve

3 (x + 1) = (x + 2) x : x = \frac{1 + 13}{2}, x = \frac{1 - 13}{2}

x = \frac{1 + 13}{2}, x = \frac{1 - 13}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 2, x = - 1

Combine undefined points with solutions:

x = \frac{1 + 13}{2}, x = \frac{1 - 13}{2}

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

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

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

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

\frac{5}{x + 1} = 1 + \frac{4}{x + 2}
