| X | + | ( | 3 2 | ÷ | 7 | ) | X | + | 5 2 | ( | 15 | ÷ | 70 | ) | X | = | 435 |
| Left side of the equation = | X | + | 3 2 | ÷ | 7 | × | X | + | 5 2 | ( | 15 | ÷ | 70 | ) | X |
| = | X | + | 3 14 | X | + | 5 2 | ( | 15 | ÷ | 70 | ) | X |
| = | 17 14 | X | + | 5 2 | ( | 15 | ÷ | 70 | ) | X |
| = | 17 14 | X | + | 5 2 | × | 15 | ÷ | 70 | × | X |
| = | 17 14 | X | + | 15 28 | X |
| = | 7 4 | X |
7 4 | X | = | 435 |
| X | = | 435 | ÷ | 7 4 |
| = | 435 | × | 4 7 |
| X | = | 1740 7 |
| X | = | 248.571429 |
