| ( | 500 | + | x | ) | × | 63 2 | = | 1623 50 | × | 500 | + | 156 5 | x |
| Left side of the equation = | 500 | × | 63 2 | + | x | × | 63 2 |
| = | 15750 | + | x | × | 63 2 |
| 15750 | + | 63 2 | x | = | 1623 50 | × | 500 | + | 156 5 | x |
| Right side of the equation = | 16230 | + | 156 5 | x |
| 15750 | + | 63 2 | x | = | 16230 | + | 156 5 | x |
63 2 | x | − | 156 5 | x | = | 16230 | − | 15750 |
3 10 | x | = | 16230 | − | 15750 |
3 10 | x | = | 480 |
| x | = | 480 | ÷ | 3 10 |
| = | 480 | × | 10 3 |
| = | 160 | × | 10 |
| x | = | 1600 |
