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

x = 5

Solution steps

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

Cross multiply

3 x - 3 = 2 x + 2

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = 5

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

\frac{x + 3}{x} = - 3

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

\frac{5}{3} = \frac{4}{y} - 1

2 = \frac{x + 7}{x - 10}
