2= 5/x

Solution

2 = \frac{5}{x}

x = \frac{5}{2}

Solution steps

2 = \frac{5}{x}

Multiply both sides by

x

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{6}{x} = \frac{2}{3}

\frac{8}{x + 3} + \frac{3}{x + 8} = 1

16 = \frac{1}{x ^{2}}

\frac{x ^{2}}{x + 120} = 60

\frac{3}{x} = 45
