उत्तर
11 + x = 19
We try several values of x until we get the L.H.S. equal to the R.H.S.
| x | L.H.S. | R.H.S. | Is L.H.S. = R.H.S.? |
| 1 | 11 + 1 = 12 | 19 | No |
| 2 | 11 + 2 = 13 | 19 | No |
| 3 | 11 + 3 = 14 | 19 | No |
| 4 | 11 + 4 = 15 | 19 | No |
| 5 | 11 + 5 = 16 | 19 | No |
| 6 | 11 + 6 = 17 | 19 | No |
| 7 | 11 + 7 = 18 | 19 | No |
| 8 | 11 + 8 = 19 | 19 | Yes |
∴ x = 8
