20 = \frac{x ^{2}}{85 - x}

x = 10 (32 - 1), x = - 10 (1 + 32)

Decimal Notation

x = 32.42640 \dots, x = - 52.42640 \dots

Solution steps

20 = \frac{x ^{2}}{85 - x}

Multiply both sides by

85 - x

20 (85 - x) = x^{2}

Solve

20 (85 - x) = x^{2} : x = 10 (32 - 1), x = - 10 (1 + 32)

x = 10 (32 - 1), x = - 10 (1 + 32)

Verify Solutions

Find undefined (singularity) points:

x = 85

Combine undefined points with solutions:

x = 10 (32 - 1), x = - 10 (1 + 32)

3.5 = \frac{0.25}{x}

\frac{10}{y} + \frac{5}{y} = 5

- \frac{6}{( x - 3 ) ^{2}} = 0

\frac{18}{x} = \frac{6}{15}

0.15 = \frac{x - 2.667}{x - 1.1}
