| 2 | ( | 5 | + | x | + | 441 10 | ) | = | 50 | + | 150 | + | 62 | − | 2 | x |
| Left side of the equation = | 2 | × | 5 | + | 2 | x | + | 2 | × | 441 10 |
| = | 10 | + | 2 | x | + | 441 5 |
| = | 491 5 | + | 2 | x |
491 5 | + | 2 | x | = | 50 | + | 150 | + | 62 | − | 2 | x |
| Right side of the equation = | 262 | − | 2 | x |
491 5 | + | 2 | x | = | 262 | − | 2 | x |
| 2 | x | + | 2 | x | = | 262 | − | 491 5 |
| 4 | x | = | 262 | − | 491 5 |
| 4 | x | = | 819 5 |
| x | = | 819 5 | ÷ | 4 |
| = | 819 5 | × | 1 4 |
| x | = | 819 20 |
| x | = | 40.95 |
