| 8 | ( | x | + | 1118 | − | 12 | x | ÷ | 10 | ) | = | 816 |
| Left side of the equation = | 8 | x | + | 8 | × | 1118 | − | 8 | × | 12 | x | ÷ | 10 |
| = | 8 | x | + | 8944 | − | 48 5 | x |
| = | - | 8 5 | x | + | 8944 |
| - | 8 5 | x | + | 8944 | = | 816 |
| - | 8 5 | x | = | 816 | − | 8944 |
| - | 8 5 | x | = | - | 8128 |
| 8128 | = | 8 5 | x |
8 5 | x | = | 8128 |
| x | = | 8128 | ÷ | 8 5 |
| = | 8128 | × | 5 8 |
| = | 1016 | × | 5 |
| x | = | 5080 |
