| ( | 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 |
| 5 | ( | 145 | x | ) | + | 56 | + | 2 | = | 3968 5 | x |
| 5 | ( | 145 | x | ) | + | 58 | = | 3968 5 | x |
| 5 | × | 145 | x | + | 58 | = | 3968 5 | x |
| 725 | x | + | 58 | = | 3968 5 | x |
| 725 | x | − | 3968 5 | x | = | - | 58 |
| - | 343 5 | x | = | - | 58 |
| 58 | = | 343 5 | x |
343 5 | x | = | 58 |
| x | = | 58 | ÷ | 343 5 |
| = | 58 | × | 5 343 |
| x | = | 290 343 |
| x | = | 0.845481 |
