L=2*(0.9)+7

Lösung

L = 2 \cdot (0.9) + 7

L = 8.8

Schritte zur Lösung

L = 2 (0.9) + 7

Vereinfache

2 (0.9) + 7 : 8.8

L = 8.8

so l v e f or x, - 4 x - y = 3

so l v e f or x, - x + 2 y = - 3

4.7 x - 4.2 - 3.3 x = 0.7 (2 x - 6)

so l v e f or y, y h = - 9 x^{4} - 5 x^{3} + 2 x

\frac{4}{3} = q + \frac{1}{3}
