0.2=(2.8x)/(0.4x^2+1.3)

Lösung

0.2 = \frac{2.8 x}{0.4 x ^{2} + 1.3}

x = \frac{2.8 + 7.7568}{0.16}, x = \frac{2.8 - 7.7568}{0.16}

0.2 (0.4 x^{2} + 1.3) = 2.8 x

Löse

0.2 (0.4 x^{2} + 1.3) = 2.8 x : x = \frac{2.8 + 7.7568}{0.16}, x = \frac{2.8 - 7.7568}{0.16}

x = \frac{2.8 + 7.7568}{0.16}, x = \frac{2.8 - 7.7568}{0.16}

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

\frac{1}{2} - \frac{1}{3 x} = - 4

3 - \frac{x}{x + 2} = 7

\frac{e}{e} = \frac{r + r}{r}

6 + \frac{1}{x + 4} = 5
