Deine neue Lieblings-Merkregel:
Rechne immer Klammer vor Punkt vor Strich!
Zuordnung
Ordne jeder Gleichung die entsprechende Lösungsmenge zu.
| 8 + x - 3 + 15 + 9x = 0 | x = -2 |
| 5(x + 9) - 7(x - 9) = 11(x - 2) | x = 10 |
| 16x + 19 = 5(4 + 3x) | x = 1 |
| 5(7x - 6) - 9(8x - 3) = 2(8 - 9x) | x = -30 |
| (3x + 2)·2 - 6x = 4 | 
|
| 5(9x - 8) - (8 + 3x)·15 = 13) | 
|
| (2 - 3x)·8 + 4x = 6 | x = 0,5 |
| 12a + 6(4 - 7a) = 9(2a + 4) | x = -0,25 |
| 6(5x - 4) - 3(10x + 2) = 10 |
|
| (2x - 5)·9,5 - 2x = -2(4 - 5x) + 13 | x = 7,5 |
| 5(7x - 6) - 9(8x - 3) = 2(8 - 9x) | x = -1 |
| } |
