| ( | x | + | 610 | − | 54 | ) | ÷ | ( | x | + | 510 | ) | = | 23 25 |
| Multiply both sides of the equation by: | ( | x | + | 510 | ) |
| ( | x | + | 610 | − | 54 | ) | = | 23 25 | ( | x | + | 510 | ) |
| x | + | 610 | − | 54 | = | 23 25 | ( | x | + | 510 | ) |
| x | + | 610 | − | 54 | = | 23 25 | x | + | 23 25 | × | 510 |
| x | + | 610 | − | 54 | = | 23 25 | x | + | 2346 5 |
| x | + | 556 | = | 23 25 | x | + | 2346 5 |
| x | − | 23 25 | x | = | 2346 5 | − | 556 |
2 25 | x | = | 2346 5 | − | 556 |
2 25 | x | = | - | 434 5 |
| x | = | - | 434 5 | ÷ | 2 25 |
| = | - | 434 5 | × | 25 2 |
| = | - | 217 | × | 5 |
| x | = | - | 1085 |
