2/(x+1)-2x=5

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

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

Decimal Notation

x = - 3, x = - 0.5

Solution steps

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

Multiply both sides by

x + 1

2 - 2 x (x + 1) = 5 (x + 1)

Solve

2 - 2 x (x + 1) = 5 (x + 1) : x = - 3, x = - \frac{1}{2}

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

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

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

D = \frac{m}{v}

\frac{8}{5 x + 2} = \frac{5}{x - 3}

\frac{4}{n + 2} = \frac{7}{n}

1 - \frac{4}{x} = \frac{5}{6}

\frac{7}{5 x - 6} = \frac{2}{2 x - 5}
