| ( | X | + | 451 50 | + | 219 25 | + | 473 50 | ) | ÷ | 4 | = | X |
| Left side of the equation = | X | × | 1 4 | + | 451 50 | × | 1 4 | + | 219 25 | × | 1 4 | + | 473 50 | × | 1 4 |
| = | X | × | 1 4 | + | 451 200 | + | 219 100 | + | 473 200 |
| = | 1 4 | X | + | 681 100 |
1 4 | X | + | 681 100 | = | X |
1 4 | X | − | X | = | - | 681 100 |
| - | 3 4 | X | = | - | 681 100 |
681 100 | = | 3 4 | X |
3 4 | X | = | 681 100 |
| X | = | 681 100 | ÷ | 3 4 |
| = | 681 100 | × | 4 3 |
| = | 227 25 | × | 1 |
| X | = | 227 25 |
| X | = | 9.08 |
