1/(1-x)=2

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

x = \frac{1}{2}

Decimal Notation

x = 0.5

Solution steps

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

Multiply both sides by

1 - x

1 = 2 (1 - x)

Switch sides

2 (1 - x) = 1

Divide both sides by

2

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

Move

1

to the right side

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

Divide both sides by

- 1

x = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = \frac{1}{2}

\frac{- 1}{6 x} + \frac{7}{6} = 1

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

\frac{8}{w - 4} - \frac{2}{w - 4} = 6

- \frac{10 x}{3 - x} = 5

y = \frac{- 1}{6 ( 3 y ^{2} + 3 )}
