| ( | x | + | 139 5 | ) | ÷ | 6 5 | = | 1 | ÷ | 9 5 |
| Left side of the equation = | x | × | 5 6 | + | 139 5 | × | 5 6 |
| = | x | × | 5 6 | + | 139 6 |
5 6 | x | + | 139 6 | = | 1 | ÷ | 9 5 |
| Right side of the equation = | 5 9 |
5 6 | x | + | 139 6 | = | 5 9 |
5 6 | x | = | 5 9 | − | 139 6 |
5 6 | x | = | - | 407 18 |
| x | = | - | 407 18 | ÷ | 5 6 |
| = | - | 407 18 | × | 6 5 |
| = | - | 407 3 | × | 1 5 |
| x | = | - | 407 15 |
| x | = | - 27.133333 |
