(2x)/(21)=(40)/(11x+4)

\frac{2 x}{21} = \frac{40}{11 x + 4}

x = 6, x = - \frac{70}{11}

Solution steps

\frac{2 x}{21} = \frac{40}{11 x + 4}

Cross multiply

2 x (11 x + 4) = 840

Solve

2 x (11 x + 4) = 840 : x = 6, x = - \frac{70}{11}

x = 6, x = - \frac{70}{11}

Verify Solutions

Find undefined (singularity) points:

x = - \frac{4}{11}

Combine undefined points with solutions:

x = 6, x = - \frac{70}{11}

\frac{2.2046}{10} = \frac{1}{x}

\frac{1}{x ^{2}} + \frac{1}{x} = 6

x + 3 = \frac{4 x + 8}{x + 3}

\frac{4}{x} = \frac{7.5}{95}

x = \frac{32}{x - 3} + 3
