| ( | X | + | 223 25 | + | 219 25 | + | 957 100 | ) | ÷ | 4 | = | X |
| Left side of the equation = | X | × | 1 4 | + | 223 25 | × | 1 4 | + | 219 25 | × | 1 4 | + | 957 100 | × | 1 4 |
| = | X | × | 1 4 | + | 223 100 | + | 219 100 | + | 957 400 |
| = | 1 4 | X | + | 109 16 |
1 4 | X | + | 109 16 | = | X |
1 4 | X | − | X | = | - | 109 16 |
| - | 3 4 | X | = | - | 109 16 |
109 16 | = | 3 4 | X |
3 4 | X | = | 109 16 |
| X | = | 109 16 | ÷ | 3 4 |
| = | 109 16 | × | 4 3 |
| = | 109 4 | × | 1 3 |
| X | = | 109 12 |
| X | = | 9.083333 |
