\frac{4.2}{3 x} = 7

x = 0.2

Solution steps

\frac{4.2}{3 x} = 7

Multiply both sides by

x

\frac{4.2}{3} = 7 x

7 x = \frac{4.2}{3}

Divide both sides by

7

x = 0.2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 0.2

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

\frac{7 x + 2}{14 x - 3} = \frac{x - 8}{2 x + 3}

\frac{5}{x + 3} = \frac{3}{x + 5}

5 = \frac{\frac{x}{150}}{\frac{80 - x}{100}}

5.9 \cdot 1 0^{- 2} = \frac{x ^{2}}{0.0288 - x}
