| X | ( | 112 100 | − | 36 100 | ) | = | ( | 5000 | + | X | ) | × | 8 100 | × | 50 100 |
| Left side of the equation = | X | × | 112 100 | − | X | × | 36 100 |
| = | 19 25 | X |
19 25 | X | = | ( | 5000 | + | X | ) | × | 8 100 | × | 50 100 |
| Right side of the equation = | ( | 5000 | + | X | ) | × | 1 25 |
19 25 | X | = | ( | 5000 | + | X | ) | × | 1 25 |
| Right side of the equation = | 5000 | × | 1 25 | + | X | × | 1 25 |
| = | 200 | + | X | × | 1 25 |
19 25 | X | = | 200 | + | 1 25 | X |
19 25 | X | − | 1 25 | X | = | 200 |
18 25 | X | = | 200 |
| X | = | 200 | ÷ | 18 25 |
| = | 200 | × | 25 18 |
| = | 100 | × | 25 9 |
| X | = | 2500 9 |
| X | = | 277.777778 |
