| 24 | × | 83 | = | ( | 38 | − | x | ) | ( | 75 | + | x | ) |
| Left side of the equation = | 1992 |
| 1992 | = | ( | 38 | − | x | ) | ( | 75 | + | x | ) |
| Right side of the equation = | 38 | ( | 75 | + | x | ) | − | x | ( | 75 | + | x | ) |
| = | 38 | × | 75 | + | 38 | x | − | x | ( | 75 | + | x | ) |
| = | 2850 | + | 38 | x | − | x | ( | 75 | + | x | ) |
| = | 2850 | + | 38 | x | − | x | × | 75 | − | x | x |
| = | 2850 | − | 37 | x | − | x | x |
| 1992 | = | 2850 | − | 37 | x | − | x | x |
