| ( | X | + | 441 50 | + | 219 25 | + | 233 25 | ) | ÷ | 4 | = | X |
| Left side of the equation = | X | × | 1 4 | + | 441 50 | × | 1 4 | + | 219 25 | × | 1 4 | + | 233 25 | × | 1 4 |
| = | X | × | 1 4 | + | 441 200 | + | 219 100 | + | 233 100 |
| = | 1 4 | X | + | 269 40 |
1 4 | X | + | 269 40 | = | X |
1 4 | X | − | X | = | - | 269 40 |
| - | 3 4 | X | = | - | 269 40 |
269 40 | = | 3 4 | X |
3 4 | X | = | 269 40 |
| X | = | 269 40 | ÷ | 3 4 |
| = | 269 40 | × | 4 3 |
| = | 269 10 | × | 1 3 |
| X | = | 269 30 |
| X | = | 8.966667 |
