427 50 | x | + | ( | 16 | − | x | ) | × | 12 5 | = | 100 |
| Left side of the equation = | 427 50 | x | + | 16 | × | 12 5 | − | x | × | 12 5 |
| = | 427 50 | x | + | 192 5 | − | x | × | 12 5 |
| = | 307 50 | x | + | 192 5 |
307 50 | x | + | 192 5 | = | 100 |
307 50 | x | = | 100 | − | 192 5 |
307 50 | x | = | 308 5 |
| x | = | 308 5 | ÷ | 307 50 |
| = | 308 5 | × | 50 307 |
| = | 308 | × | 10 307 |
| x | = | 3080 307 |
| x | = | 10.032573 |
