(x-1)/(x+1)= 5/3

\frac{x - 1}{x + 1} = \frac{5}{3}

x = - 4

Solution steps

\frac{x - 1}{x + 1} = \frac{5}{3}

Cross multiply

3 x - 3 = 5 x + 5

Move

3

to the right side

3 x = 5 x + 8

Move

5 x

to the left side

- 2 x = 8

Divide both sides by

- 2

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = - 4

\frac{5}{3} = \frac{40}{x}

\frac{x ^{2} + x - 12}{x - 3} = x + 4

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

103 = \frac{( 2 x - 3 )}{10 - 6 x}

\frac{0.49}{x} = \frac{x}{0.64}
