Übungsaufgaben
- x + 14 = 20
Lösung
x = 6
- x + 14 = 20 | − 14
- x = 20 − 14 = 6
- x + 3 = 15
Lösung
x = 12
- x + 3 = 15 | − 3
- x = 15 − 3 = 12
- 6x = 18
Lösung
x = 3
- 6x = 18 | ÷ 6
- x = 18 ÷ 6 = 3
- 2x + 3 = 13
Lösung
x = 5
- 2x + 3 = 13 | − 3
- 2x = 10 | ÷ 2
- x = 5
- 4(x − 14) = −12
Lösung
x = 11
- 4(x − 14) = −12 | ÷ 4
- x − 14 = −3 | + 14
- x = 11
- x + 1 = 11
Lösung
x = 10
- x + 1 = 11 | − 1
- x = 11 − 1 = 10
