47 10 | × | 900 | + | 5 | X | = | 24 5 | ( | 900 | + | X | ) |
| Left side of the equation = | 4230 | + | 5 | X |
| 4230 | + | 5 | X | = | 24 5 | ( | 900 | + | X | ) |
| Right side of the equation = | 24 5 | × | 900 | + | 24 5 | X |
| = | 4320 | + | 24 5 | X |
| 4230 | + | 5 | X | = | 4320 | + | 24 5 | X |
| 5 | X | − | 24 5 | X | = | 4320 | − | 4230 |
1 5 | X | = | 4320 | − | 4230 |
1 5 | X | = | 90 |
| X | = | 90 | ÷ | 1 5 |
| = | 90 | × | 5 |
| X | = | 450 |
