| 2 | ( | 5 | + | 36 | + | x | ) | = | 442 5 | + | 200 | − | 2 | x |
| Left side of the equation = | 2 | × | 5 | + | 2 | × | 36 | + | 2 | x |
| = | 10 | + | 72 | + | 2 | x |
| = | 82 | + | 2 | x |
| 82 | + | 2 | x | = | 442 5 | + | 200 | − | 2 | x |
| Right side of the equation = | 1442 5 | − | 2 | x |
| 82 | + | 2 | x | = | 1442 5 | − | 2 | x |
| 2 | x | + | 2 | x | = | 1442 5 | − | 82 |
| 4 | x | = | 1442 5 | − | 82 |
| 4 | x | = | 1032 5 |
| x | = | 1032 5 | ÷ | 4 |
| = | 1032 5 | × | 1 4 |
| = | 258 5 | × | 1 |
| x | = | 258 5 |
| x | = | 51.6 |
