| ( | ( | x | − | 4 | ) | ÷ | ( | x | + | 4 | ) | ) | = | 1119 2000 |
| ( | x | − | 4 | ) | ÷ | ( | x | + | 4 | ) | = | 1119 2000 |
| Multiply both sides of the equation by: | ( | x | + | 4 | ) |
| ( | x | − | 4 | ) | = | 1119 2000 | ( | x | + | 4 | ) |
| x | − | 4 | = | 1119 2000 | ( | x | + | 4 | ) |
| x | − | 4 | = | 1119 2000 | x | + | 1119 2000 | × | 4 |
| x | − | 4 | = | 1119 2000 | x | + | 1119 500 |
| x | − | 1119 2000 | x | = | 1119 500 | + | 4 |
881 2000 | x | = | 1119 500 | + | 4 |
881 2000 | x | = | 3119 500 |
| x | = | 3119 500 | ÷ | 881 2000 |
| = | 3119 500 | × | 2000 881 |
| = | 3119 | × | 4 881 |
| x | = | 12476 881 |
| x | = | 14.16118 |
