(x-1)/4 = 2/(x+1)

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

x = 3, x = - 3

Solution steps

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

Cross multiply

(x - 1) (x + 1) = 8

Solve

(x - 1) (x + 1) = 8 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = 3, x = - 3

\frac{11}{x} = \frac{12}{x + 1}

\frac{45}{x - 2} = 9

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

0 = 4 + \frac{5}{x ^{2} + 2}

\frac{3}{x + 8} = \frac{10}{2 x - 9}
