= | 3 8800 | X | − | 3 11 | − | 3 22 | × | 1 | + | 3 22 | × | 25 100 |
= | 3 8800 | X | − | 3 11 | − | 3 22 | + | 3 88 |
= | 3 8800 | X | − | 3 8 |
3 8800 | X | − | 3 8 | = | 0 |
3 8800 | X | = | 0 | + | 3 8 |
3 8800 | X | = | 3 8 |
X | = | 3 8 | ÷ | 3 8800 |
= | 3 8 | × | 8800 3 |
= | 1 | × | 1100 |
X | = | 1100 |
