( | 1 | − | 10 100 | ) | X | + | 2 | = | X | − | 10 | − | 8 |
Left side of the equation = | 1 | X | − | 10 100 | X | + | 2 |
= | 9 10 | X | + | 2 |
9 10 | X | + | 2 | = | X | − | 10 | − | 8 |
Right side of the equation = | X | − | 18 |
9 10 | X | + | 2 | = | X | − | 18 |
9 10 | X | − | X | = | - | 18 | − | 2 |
- | 1 10 | X | = | - | 18 | − | 2 |
- | 1 10 | X | = | - | 20 |
20 | = | 1 10 | X |
1 10 | X | = | 20 |
X | = | 20 | ÷ | 1 10 |
= | 20 | × | 10 |
X | = | 200 |
