5/x =2

Solution

\frac{5}{x} = 2

x = \frac{5}{2}

Solution steps

\frac{5}{x} = 2

Multiply both sides by

x

5 = 2 x

Switch sides

2 x = 5

Divide both sides by

2

x = \frac{5}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{5}{2}

\frac{4 a - 1}{a - 1} = 3

\frac{1}{x} = \frac{4}{100}

y, x = \frac{1}{y ^{3}}

3 = \frac{7}{r - 6}

\frac{x}{x + 1} = \frac{3}{2}
