| ( | 5 | ( | 145 | x | ) | × | 4 | × | 14 | + | 2 | ) | ÷ | ( | 160 | x | ) | = | 124 25 |
| Multiply both sides of the equation by: | ( | 160 | x | ) |
| ( | 5 | ( | 145 | x | ) | × | 4 | × | 14 | + | 2 | ) | = | 124 25 | ( | 160 | x | ) |
| 5 | ( | 145 | x | ) | × | 4 | × | 14 | + | 2 | = | 124 25 | ( | 160 | x | ) |
| 5 | ( | 145 | x | ) | × | 4 | × | 14 | + | 2 | = | 124 25 | × | 160 | x |
| 280 | ( | 145 | x | ) | + | 2 | = | 3968 5 | x |
| 280 | × | 145 | x | + | 2 | = | 3968 5 | x |
| 40600 | x | + | 2 | = | 3968 5 | x |
| 40600 | x | − | 3968 5 | x | = | - | 2 |
