| ( | 60 | + | X | ) | × | 6 | = | ( | 48 | + | X | ) | × | 7 |
| Left side of the equation = | 60 | × | 6 | + | X | × | 6 |
| = | 360 | + | X | × | 6 |
| 360 | + | 6 | X | = | ( | 48 | + | X | ) | × | 7 |
| Right side of the equation = | 48 | × | 7 | + | X | × | 7 |
| = | 336 | + | X | × | 7 |
| 360 | + | 6 | X | = | 336 | + | 7 | X |
| 6 | X | − | 7 | X | = | 336 | − | 360 |
| - | X | = | 336 | − | 360 |
| - | X | = | 336 | − | 360 |
| - | X | = | - | 24 |
| 24 | = | X |
| X | = | 24 |
