(600)/(300+x)=(400)/(300-x)

\frac{600}{300 + x} = \frac{400}{300 - x}

x = 60

Solution steps

\frac{600}{300 + x} = \frac{400}{300 - x}

Cross multiply

180000 - 600 x = 120000 + 400 x

Move

180000

to the right side

- 600 x = 400 x - 60000

Move

400 x

to the left side

- 1000 x = - 60000

Divide both sides by

- 1000

x = 60

Verify Solutions

Find undefined (singularity) points:

x = - 300, x = 300

Combine undefined points with solutions:

x = 60

\frac{3}{4 ( 2 x - 3 )} = 1

1 - \frac{3}{x} = 0

b, \frac{d}{b} = (\frac{n}{q})^{3}

y, \frac{1}{x} + \frac{3}{y + 1} = \frac{5}{4}
