| Left side of the equation = | - | 4082750 | + | 3000000 | + | x | − | 45 | − | x | × | 1 40 |
| = | - | 1082795 | + | 39 40 | x |
| - | 1082795 | + | 39 40 | x | = | 300000 |
39 40 | x | = | 300000 | + | 1082795 |
39 40 | x | = | 1382795 |
| x | = | 1382795 | ÷ | 39 40 |
| = | 1382795 | × | 40 39 |
| x | = | 55311800 39 |
