(4x^2)/(40x)=3

\frac{4 x ^{2}}{40 x} = 3

x = 30

Solution steps

\frac{4 x ^{2}}{40 x} = 3

Simplify

\frac{4 x ^{2}}{40 x} : \frac{x}{10}

\frac{x}{10} = 3

Multiply both sides by

10

x = 30

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 30

\frac{x ^{2} - x}{x + 2} = \frac{2 x - 4}{x - 2}

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

\frac{4.5351}{398.15} = \frac{3.8}{x}

\frac{x + 4}{4 x + 7} = \frac{x - 3}{x ^{2} - x - 6}

\frac{3 x - 1}{6 x - 2} = \frac{2 x + 5}{4 x - 13}
