9 = \frac{121}{4 + x ^{2}}

x = \frac{85}{3}, x = - \frac{85}{3}

Decimal Notation

x = 3.07318 \dots, x = - 3.07318 \dots

Solution steps

9 = \frac{121}{4 + x ^{2}}

Multiply both sides by

4 + x^{2}

9 (4 + x^{2}) = 121

Solve

9 (4 + x^{2}) = 121 : x = \frac{85}{3}, x = - \frac{85}{3}

x = \frac{85}{3}, x = - \frac{85}{3}

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

4 = \frac{R}{10000 + R}

\frac{- 2 + \frac{14}{13}}{x + 2} = 1

\frac{350}{x} = 3.5

\frac{4}{x + 1} = \frac{3}{7}
