| x | ÷ | 87 | ÷ | ( | 15 | ÷ | 1000 | + | 20 | ÷ | 1650 | ) | × | 1000 | = | 2 |
| Multiply both sides of the equation by: | ( | 15 | ÷ | 1000 | + | 20 | ÷ | 1650 | ) |
| x | ÷ | 87 | × | 1000 | = | 2 | ( | 15 | ÷ | 1000 | + | 20 | ÷ | 1650 | ) |
| x | ÷ | 87 | × | 1000 | = | 2 | × | 15 | ÷ | 1000 | + | 2 | × | 20 | ÷ | 1650 |
| x | × | 1000 87 | = | 3 100 | + | 4 165 |
1000 87 | x | = | 179 3300 |
| x | = | 179 3300 | ÷ | 1000 87 |
| = | 179 3300 | × | 87 1000 |
| = | 179 1100 | × | 29 1000 |
| x | = | 5191 1100000 |
