2= 2/x

Solution

2 = \frac{2}{x}

x = 1

Solution steps

2 = \frac{2}{x}

Multiply both sides by

x

2 x = 2

Divide both sides by

2

x = 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1

\frac{16 - x ^{2}}{2 x - 8} = 0

\frac{3 y + 9}{4 y - 5} = 6

0 = \frac{2 x}{1 + x ^{2}}

\frac{2}{3} = \frac{4}{x}

\frac{27}{x} = \frac{51}{8}
