8/x =4

Solution

\frac{8}{x} = 4

x = 2

Solution steps

\frac{8}{x} = 4

Multiply both sides by

x

8 = 4 x

Switch sides

4 x = 8

Divide both sides by

4

x = 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2

4 = \frac{6}{x}

\frac{5}{y + 3} - 2 = \frac{5}{y + 3}

\frac{12 x ^{2} - 4}{4 x - 1} = 3 x

\frac{1}{x - 1} + \frac{3}{4 - x} = 0

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