| x | − | 2020 | − | ( | x | × | 12 100 | ÷ | 4 | ) | = | 100 |
| Left side of the equation = | x | − | 2020 | − | x | × | 12 100 | ÷ | 4 |
| = | x | − | 2020 | − | x | × | 3 100 |
| = | 97 100 | x | − | 2020 |
97 100 | x | − | 2020 | = | 100 |
97 100 | x | = | 100 | + | 2020 |
97 100 | x | = | 2120 |
| x | = | 2120 | ÷ | 97 100 |
| = | 2120 | × | 100 97 |
| x | = | 212000 97 |
| x | = | 2185.56701 |
