1/(x+1)=2

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

x = - \frac{1}{2}

Solution steps

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

Multiply both sides by

x + 1

1 = 2 (x + 1)

Switch sides

2 (x + 1) = 1

Divide both sides by

2

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

Move

1

to the right side

x = - \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = - \frac{1}{2}

\frac{y + 4}{2 y - 3} = \frac{3}{5}

\frac{5 x - 4}{2} = \frac{12}{2 x}

\frac{4}{x} = \frac{1}{14}

\frac{5}{x + 4} - 8 = 0

0.25 = \frac{25}{x}
