erweitern (3a+4c=8,2)-(2a+3c=58)

Lösung

erweitern

(3 a + 4 c = 8, 2) - (2 a + 3 c = 58)

(3 a + 4 c = 8, 2) - 2 a - 3 c = 58

Schritte zur Lösung

(3 a + 4 c = 8, 2) - (2 a + 3 c = 58)

= (3 a + 4 \cdot 8 \cdot 2 =, c) - (2 a + 3 \cdot 58 = c)

- (2 a + 3 c = 58) : - 2 a - 3 c = 58

(3 a + 4 c = 8, 2) - 2 a - 3 c = 58
