\frac{20}{x} = \frac{0.8}{0.4}

x = 10

Solution steps

\frac{20}{x} = \frac{0.8}{0.4}

0.8

x = 10

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 10

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

\frac{2 π}{b} = 2 π

\frac{3 p - 8}{4 p} = \frac{4}{3}

\frac{2 π}{b} = 12

2 + \frac{7}{b} = \frac{3}{5}
