X | − | ( | X | − | 10000 | ) | × | 3 100 | = | 12000 |
Left side of the equation = | X | − | X | × | 3 100 | + | 10000 | × | 3 100 |
= | X | − | X | × | 3 100 | + | 300 |
= | 97 100 | X | + | 300 |
97 100 | X | + | 300 | = | 12000 |
97 100 | X | = | 12000 | − | 300 |
97 100 | X | = | 11700 |
X | = | 11700 | ÷ | 97 100 |
= | 11700 | × | 100 97 |
X | = | 1170000 97 |
X | = | 12061.85567 |
