| 2 | ( | x | + | 5 | ) | = | 50 | + | 442 5 | + | 242 | − | 2 | x |
| Left side of the equation = | 2 | x | + | 2 | × | 5 |
| = | 2 | x | + | 10 |
| 2 | x | + | 10 | = | 50 | + | 442 5 | + | 242 | − | 2 | x |
| Right side of the equation = | 1902 5 | − | 2 | x |
| 2 | x | + | 10 | = | 1902 5 | − | 2 | x |
| 2 | x | + | 2 | x | = | 1902 5 | − | 10 |
| 4 | x | = | 1902 5 | − | 10 |
| 4 | x | = | 1852 5 |
| x | = | 1852 5 | ÷ | 4 |
| = | 1852 5 | × | 1 4 |
| = | 463 5 | × | 1 |
| x | = | 463 5 |
| x | = | 92.6 |
