(15)/z = 4/8

\frac{15}{z} = \frac{4}{8}

z = 30

Solution steps

\frac{15}{z} = \frac{4}{8}

Cross multiply

120 = z \cdot 4

Switch sides

z \cdot 4 = 120

Divide both sides by

4

z = 30

Verify Solutions

Find undefined (singularity) points:

z = 0

Combine undefined points with solutions:

z = 30

d, \frac{ab}{d} + c = e

1 + \frac{6}{y - 2} = \frac{3 y}{y - 2}

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

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

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