x/(x+40)=(40)/(x-20)

\frac{x}{x + 40} = \frac{40}{x - 20}

x = 80, x = - 20

Solution steps

\frac{x}{x + 40} = \frac{40}{x - 20}

Cross multiply

x (x - 20) = (x + 40) \cdot 40

Solve

x (x - 20) = (x + 40) \cdot 40 : x = 80, x = - 20

x = 80, x = - 20

Verify Solutions

Find undefined (singularity) points:

x = - 40, x = 20

Combine undefined points with solutions:

x = 80, x = - 20

\frac{39.9}{x} = 2.1

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

\frac{24}{52} = \frac{96}{m}

\frac{22}{x} = - 11

\frac{x}{x - 8} + 7 = \frac{8}{x - 8}
