| 4586 | + | ( | x | − | 9 2 | ) | × | 9 2 | = | 5920 |
| Left side of the equation = | 4586 | + | x | × | 9 2 | − | 9 2 | × | 9 2 |
| = | 4586 | + | x | × | 9 2 | − | 81 4 |
| = | 18263 4 | + | 9 2 | x |
18263 4 | + | 9 2 | x | = | 5920 |
9 2 | x | = | 5920 | − | 18263 4 |
9 2 | x | = | 5417 4 |
| x | = | 5417 4 | ÷ | 9 2 |
| = | 5417 4 | × | 2 9 |
| = | 5417 2 | × | 1 9 |
| x | = | 5417 18 |
| x | = | 300.944444 |
