| 10 | x | ÷ | 3 | = | 16 | ( | 85 | − | x | ) | ÷ | 2 |
| Left side of the equation = | 10 3 | x |
10 3 | x | = | 16 | ( | 85 | − | x | ) | ÷ | 2 |
| Right side of the equation = | 8 | ( | 85 | − | x | ) |
10 3 | x | = | 8 | ( | 85 | − | x | ) |
| Right side of the equation = | 8 | × | 85 | − | 8 | x |
| = | 680 | − | 8 | x |
10 3 | x | = | 680 | − | 8 | x |
10 3 | x | + | 8 | x | = | 680 |
34 3 | x | = | 680 |
| x | = | 680 | ÷ | 34 3 |
| = | 680 | × | 3 34 |
| = | 20 | × | 3 |
| x | = | 60 |
