Lösung

r = 102 - 78 + 232

r = 42

Dezimale

r = 5.65685 \dots

Schritte zur Lösung

r = 102 - 78 + 232

Vereinfache

102 - 78 + 232 : 42

r = 42

so l v e f or x, 5 x + 10 y = 50

\frac{z}{2 - i} = - 1 + i 2

so l v e f or x, 2 y = 8 x + 8

- 25 + \frac{3}{11} z = - 16

so l v e f or x, 6 x - 2 y = 8
