| ( | 1310 | − | 150 | x | ) | ÷ | 150 | + | 150 | x | = | 1310 |
| Left side of the equation = | 1310 | × | 1 150 | − | 150 | x | × | 1 150 | + | 150 | x |
| = | 131 15 | − | 1 | x | + | 150 | x |
| = | 131 15 | + | 149 | x |
131 15 | + | 149 | x | = | 1310 |
| 149 | x | = | 1310 | − | 131 15 |
| 149 | x | = | 19519 15 |
| x | = | 19519 15 | ÷ | 149 |
| = | 19519 15 | × | 1 149 |
| x | = | 19519 2235 |
| x | = | 8.733333 |
