(400)/x =(160)/(x-3)

\frac{400}{x} = \frac{160}{x - 3}

x = 5

Solution steps

\frac{400}{x} = \frac{160}{x - 3}

Cross multiply

400 x - 1200 = x \cdot 160

Move

1200

to the right side

400 x = x \cdot 160 + 1200

Move

x 160

to the left side

240 x = 1200

Divide both sides by

240

x = 5

Verify Solutions

Find undefined (singularity) points:

x = 0, x = 3

Combine undefined points with solutions:

x = 5

\frac{x}{x - 8} = \frac{8}{x - 8} + 9

x, \frac{- 2}{5 x - 5 y} = 3

\frac{( x ^{4} - 1 )}{x ^{3}} = 0

2 x - 3 - \frac{x ^{2} + 1}{x - 2} = - 7

x, \frac{x - y}{2 x} = 3
