( | X | × | 17 20 | ) | + | 1700 | − | X | = | 17000 |
Left side of the equation = | X | × | 17 20 | + | 1700 | − | X |
= | - | 3 20 | X | + | 1700 |
- | 3 20 | X | + | 1700 | = | 17000 |
- | 3 20 | X | = | 17000 | − | 1700 |
- | 3 20 | X | = | 15300 |
- | 15300 | = | 3 20 | X |
3 20 | X | = | - | 15300 |
X | = | - | 15300 | ÷ | 3 20 |
= | - | 15300 | × | 20 3 |
= | - | 5100 | × | 20 |
X | = | - | 102000 |
