| 2 | m | + | 1 | = | - | ( | 2 | m | + | 11 | ) | ÷ | 19 |
| Right side of the equation = | - | 2 | m | × | 1 19 | − | 11 | × | 1 19 |
| = | - | 2 19 | m | − | 11 19 |
| 2 | m | + | 1 | = | - | 2 19 | m | − | 11 19 |
| 2 | m | + | 2 19 | m | = | - | 11 19 | − | 1 |
40 19 | m | = | - | 11 19 | − | 1 |
40 19 | m | = | - | 30 19 |
| m | = | - | 30 19 | ÷ | 40 19 |
| = | - | 30 19 | × | 19 40 |
| = | - | 3 | × | 1 4 |
| m | = | - | 3 4 |
| m | = | - 0.75 |
