10=(20*r)/(600+r)

10 = \frac{20 \cdot r}{600 + r}

r = 600

Solution steps

10 = \frac{20 r}{600 + r}

Multiply both sides by

600 + r

10 (600 + r) = 20 r

Expand

10 (600 + r) : 6000 + 10 r

6000 + 10 r = 20 r

Move

6000

to the right side

10 r = 20 r - 6000

Move

20 r

to the left side

- 10 r = - 6000

Divide both sides by

- 10

r = 600

Verify Solutions

Find undefined (singularity) points:

r = - 600

Combine undefined points with solutions:

r = 600

x (\frac{4 - x}{x}) + x = 4

\frac{15}{x} + 6 = \frac{9}{2 x}

\frac{3 x - 2}{5} = \frac{8}{x}

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

x, R = \frac{y}{x} x^{100}
