| 1 | ÷ | 3 | × | x | + | 1 | ÷ | 10 | × | ( | 100 | − | x | ) | = | 24 |
| Left side of the equation = | 1 3 | x | + | 1 10 | ( | 100 | − | x | ) |
1 3 | x | + | 1 10 | ( | 100 | − | x | ) | = | 24 |
| Left side of the equation = | 1 3 | x | + | 1 10 | × | 100 | − | 1 10 | x |
| = | 1 3 | x | + | 10 | − | 1 10 | x |
| = | 7 30 | x | + | 10 |
7 30 | x | + | 10 | = | 24 |
7 30 | x | = | 24 | − | 10 |
7 30 | x | = | 14 |
| x | = | 14 | ÷ | 7 30 |
| = | 14 | × | 30 7 |
| = | 2 | × | 30 |
| x | = | 60 |
