| 8 | x | = | 3 | ÷ | 1 | × | ( | 850 | − | 10 | x | ) |
| Right side of the equation = | 3 | ( | 850 | − | 10 | x | ) |
| 8 | x | = | 3 | ( | 850 | − | 10 | x | ) |
| Right side of the equation = | 3 | × | 850 | − | 3 | × | 10 | x |
| = | 2550 | − | 30 | x |
| 8 | x | = | 2550 | − | 30 | x |
| 8 | x | + | 30 | x | = | 2550 |
| 38 | x | = | 2550 |
| x | = | 2550 | ÷ | 38 |
| = | 2550 | × | 1 38 |
| = | 1275 | × | 1 19 |
| x | = | 1275 19 |
| x | = | 67.105263 |
