| ( | X | − | 69 10 | ) | × | 87 50 | = | 33 2 |
| Left side of the equation = | X | × | 87 50 | − | 69 10 | × | 87 50 |
| = | X | × | 87 50 | − | 6003 500 |
87 50 | X | − | 6003 500 | = | 33 2 |
87 50 | X | = | 33 2 | + | 6003 500 |
87 50 | X | = | 14253 500 |
| X | = | 14253 500 | ÷ | 87 50 |
| = | 14253 500 | × | 50 87 |
| = | 4751 10 | × | 1 29 |
| X | = | 4751 290 |
| X | = | 16.382759 |
