| 16 | + | x | = | ( | 128 | + | x | ) | × | 3 | ÷ | 5 |
| Right side of the equation = | ( | 128 | + | x | ) | × | 3 5 |
| 16 | + | x | = | ( | 128 | + | x | ) | × | 3 5 |
| Right side of the equation = | 128 | × | 3 5 | + | x | × | 3 5 |
| = | 384 5 | + | x | × | 3 5 |
| 16 | + | x | = | 384 5 | + | 3 5 | x |
| x | − | 3 5 | x | = | 384 5 | − | 16 |
2 5 | x | = | 384 5 | − | 16 |
2 5 | x | = | 304 5 |
| x | = | 304 5 | ÷ | 2 5 |
| = | 304 5 | × | 5 2 |
| = | 152 | × | 1 |
| x | = | 152 |
