| x | × | 3 50 | ÷ | 1 | + | ( | x | × | 3 50 | ) | = | 99 100 |
| Left side of the equation = | x | × | 3 50 | + | ( | x | × | 3 50 | ) |
3 50 | x | + | ( | x | × | 3 50 | ) | = | 99 100 |
| Left side of the equation = | 3 50 | x | + | x | × | 3 50 |
| = | 3 25 | x |
3 25 | x | = | 99 100 |
| x | = | 99 100 | ÷ | 3 25 |
| = | 99 100 | × | 25 3 |
| = | 33 4 | × | 1 |
| x | = | 33 4 |
| x | = | 8.25 |
