0=1-(2*1)/x

0 = 1 - \frac{2 \cdot 1}{x}

x = 2

Solution steps

0 = 1 - \frac{2 \cdot 1}{x}

Move

1

to the left side

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

Simplify

- \frac{2 \cdot 1}{x} : - \frac{2}{x}

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

Multiply both sides by

x

- x = - 2

Divide both sides by

- 1

x = 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2

x + \frac{9}{x} = - 10

\frac{u + 2}{3 u - 1} + 1 = \frac{6 - u}{u + 1}

\frac{1}{x ^{2}} + \frac{3}{x} - 10 = 0

\frac{50}{x + 5} = \frac{x}{10} + 4.5

\frac{2}{x} + \frac{x + 6}{4} = 0
