Lösung

7.3 x - 47.7 = 1.5 (x - 0)

x = \frac{69867 + 6986 7 ^{2} - 4850008164}{10658}

Dezimale

x = 7.08103 \dots

Schritte zur Lösung

7.3 x - 47.7 = 1.5 (x - 0)

Quadriere beide Seiten:

53.29 x^{2} - 696.42 x + 2275.29 = 2.25 x

53.29 x^{2} - 696.42 x + 2275.29 = 2.25 x

Löse

53.29 x^{2} - 696.42 x + 2275.29 = 2.25 x : x = \frac{69867 + 6986 7 ^{2} - 4850008164}{10658}, x = \frac{69867 - 6986 7 ^{2} - 4850008164}{10658}

x = \frac{69867 + 6986 7 ^{2} - 4850008164}{10658}, x = \frac{69867 - 6986 7 ^{2} - 4850008164}{10658}

Wahr

, x = \frac{69867 - 6986 7 ^{2} - 4850008164}{10658}

Falsch

Deshalb ist die Lösung

x = \frac{69867 + 6986 7 ^{2} - 4850008164}{10658}

x^{2} = 2

so l v e f or f, f (x + 9) = x + 9

x - 2 = x + 1

x - 2 = x + 2

2 x - 5 = 4 x - 7
