(18)/x =6

Solution

\frac{18}{x} = 6

x = 3

Solution steps

\frac{18}{x} = 6

Multiply both sides by

x

18 = 6 x

Switch sides

6 x = 18

Divide both sides by

6

x = 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 3

\frac{4}{x} = \frac{2}{21}

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

x^{- 2} + 2 x + 1 = 0

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

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