| 10 | × | 5800 | + | 5800 | x | × | 70 | = | 5800 | x | × | 85 100 |
| Left side of the equation = | 58000 | + | 406000 | x |
| 58000 | + | 406000 | x | = | 5800 | x | × | 85 100 |
| Right side of the equation = | 4930 | x |
| 58000 | + | 406000 | x | = | 4930 | x |
| 406000 | x | − | 4930 | x | = | - | 58000 |
| 401070 | x | = | - | 58000 |
| x | = | - | 58000 | ÷ | 401070 |
| = | - | 58000 | × | 1 401070 |
| = | - | 200 | × | 1 1383 |
| x | = | - | 200 1383 |
| x | = | - 0.144613 |
