7/(5(x+1/2)-0.7)=3(-x-1.2)+5

Lösung

\frac{7}{5 ( x + \frac{1}{2} ) - 0.7} = 3 (- x - 1.2) + 5

x = \frac{1.6}{30} - i \frac{266.24}{30}, x = \frac{1.6}{30} + i \frac{266.24}{30}

5 (x + \frac{1}{2}) - 0.7

7 = 3 (- x - 1.2) (5 (x + \frac{1}{2}) - 0.7) + 5 (5 (x + \frac{1}{2}) - 0.7)

Löse

7 = 3 (- x - 1.2) (5 (x + \frac{1}{2}) - 0.7) + 5 (5 (x + \frac{1}{2}) - 0.7) : x = \frac{1.6}{30} - i \frac{266.24}{30}, x = \frac{1.6}{30} + i \frac{266.24}{30}

x = \frac{1.6}{30} - i \frac{266.24}{30}, x = \frac{1.6}{30} + i \frac{266.24}{30}

4 \cdot (\frac{10}{x})^{2} - 6 \cdot (\frac{10}{x})^{2} + 3 \cdot (\frac{10}{x})^{2} = 1

\frac{( 1 + x )}{( 11 - x )} = \frac{1}{3}

so l v e f or x, 9 \frac{y}{x} = 2

so l v e f or x, x^{2} + (y - \frac{4}{x ^{2}}) 2 = 2
