4/(x-1)=(x+1)/(12)

\frac{4}{x - 1} = \frac{x + 1}{12}

x = 7, x = - 7

Solution steps

\frac{4}{x - 1} = \frac{x + 1}{12}

Cross multiply

48 = (x - 1) (x + 1)

Solve

48 = (x - 1) (x + 1) : x = 7, x = - 7

x = 7, x = - 7

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = 7, x = - 7

\frac{1}{3 ( t + 6 ) - 10} = - 3 t + 2

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

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

y, x = \frac{y - 5}{y - 2}

\frac{6}{x} + \frac{4}{x + 9} = 9
