(20)=((70x)/(70+x))

(20) = (\frac{70 x}{70 + x})

x = 28

Solution steps

(20) = (\frac{70 x}{70 + x})

Simplify

(\frac{70 x}{70 + x}) : \frac{70 x}{70 + x}

(20) = \frac{70 x}{70 + x}

Multiply both sides by

70 + x

20 (70 + x) = 70 x

Expand

20 (70 + x) : 1400 + 20 x

1400 + 20 x = 70 x

Move

1400

to the right side

20 x = 70 x - 1400

Move

70 x

to the left side

- 50 x = - 1400

Divide both sides by

- 50

x = 28

Verify Solutions

Find undefined (singularity) points:

x = - 70

Combine undefined points with solutions:

x = 28

\frac{5}{2 x} = \frac{5}{6 x ^{2}}

\frac{9}{16} + \frac{1}{b ^{2}} = 1

\frac{9}{x - 6} = \frac{3}{5}

x = \frac{3}{x}

0 = \frac{3 x}{4 - x ^{2}}
