| ( | 1198 | ( | 1 | + | 20 100 | ) | ) | + | ( | 4 100 | x | ) | = | x |
| Left side of the equation = | 1198 | ( | 1 | + | 20 100 | ) | + | ( | 4 100 | x | ) |
| = | 1198 | × | 1 | + | 1198 | × | 20 100 | + | ( | 4 100 | x | ) |
| = | 1198 | + | 1198 5 | + | ( | 4 100 | x | ) |
| = | 7188 5 | + | ( | 4 100 | x | ) |
| = | 7188 5 | + | 4 100 | x |
7188 5 | + | 4 100 | x | = | x |
4 100 | x | − | x | = | - | 7188 5 |
| - | 24 25 | x | = | - | 7188 5 |
7188 5 | = | 24 25 | x |
24 25 | x | = | 7188 5 |
| x | = | 7188 5 | ÷ | 24 25 |
| = | 7188 5 | × | 25 24 |
| = | 599 | × | 5 2 |
| x | = | 2995 2 |
| x | = | 1497.5 |
