| ( | x | + | 610 | − | 54 | ) | ÷ | ( | x | + | 610 | ) | = | 23 25 |
| Multiply both sides of the equation by: | ( | x | + | 610 | ) |
| ( | x | + | 610 | − | 54 | ) | = | 23 25 | ( | x | + | 610 | ) |
| x | + | 610 | − | 54 | = | 23 25 | ( | x | + | 610 | ) |
| x | + | 610 | − | 54 | = | 23 25 | x | + | 23 25 | × | 610 |
| x | + | 610 | − | 54 | = | 23 25 | x | + | 2806 5 |
| x | + | 556 | = | 23 25 | x | + | 2806 5 |
| x | − | 23 25 | x | = | 2806 5 | − | 556 |
2 25 | x | = | 2806 5 | − | 556 |
2 25 | x | = | 26 5 |
| x | = | 26 5 | ÷ | 2 25 |
| = | 26 5 | × | 25 2 |
| = | 13 | × | 5 |
| x | = | 65 |
