| Question | Answer |
| x+5=15 | x=10 |
| 2x+5=15 | x=5 |
| 3x=15 | x=5 |
| 3x+5=20 | x=5 |
| 0,5x=4 | x=8 |
| 0,5x+5=10 | x=10 |
| 1/3 x = 13 | x=39 |
| 1/3 x -4 = 5 | x=27 |
| 0,1 x = 3 | x = 30 |
| 1,1 x = 77 | x = 70 |
| 0,7 x = 2,1 | x =3 |
| 0,5 (x-4) = 4 | x=12 |
| -2 (x+3) = 12 | x=-9 |
| 2- ( 2x-(6+2x))-x=0 | x=8 |
| x-(2-(2-(2-(2-x))))=0 | równanie tożsamościowe czyli nieoznaczone, ma nieskończenie wiele rozwiazań |
| x-(x-(x-3))=0 | x=3 |
