x= b/(a/2)

Lösung

x = \frac{b}{\frac{a}{2}}

x = \frac{2 b}{a}

Schritte zur Lösung

x = \frac{b}{\frac{a}{2}}

Wende Bruchregel an:

\frac{a}{\frac{b}{c}} = \frac{a \cdot c}{b}

x = \frac{2 b}{a}

so l v e f or x, 2 x + 5 y + 2 z = - 38

x + 18 = 162

3 = - 2 x + 5

3 (x - 2) = - 12

so l v e f or f, c = \frac{5 ( f - 32 )}{9}
