0.4 = \frac{6 x}{x ^{2} + 4}

x = \frac{15 + 209}{2}, x = \frac{15 - 209}{2}

Decimal Notation

x = 14.72841 \dots, x = 0.27158 \dots

Solution steps

0.4 = \frac{6 x}{x ^{2} + 4}

Multiply both sides by

x^{2} + 4

0.4 (x^{2} + 4) = 6 x

Solve

0.4 (x^{2} + 4) = 6 x : x = \frac{15 + 209}{2}, x = \frac{15 - 209}{2}

x = \frac{15 + 209}{2}, x = \frac{15 - 209}{2}

\frac{100 \cdot x}{100 + x} = 40

\frac{1350}{x} = 0.16

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

\frac{8}{x} = \frac{32}{20}

f^{- 1} (0.5) = 1.4 \cdot 0. 8^{0.5}
