| 13 | ÷ | 24 | × | 3 5 | + | 2 5 | x | = | 11 | ÷ | 24 | × | 3 5 | + | ( | 1 | − | x | ) | × | 2 5 |
| Left side of the equation = | 13 40 | + | 2 5 | x |
13 40 | + | 2 5 | x | = | 11 | ÷ | 24 | × | 3 5 | + | ( | 1 | − | x | ) | × | 2 5 |
| Right side of the equation = | 11 40 | + | ( | 1 | − | x | ) | × | 2 5 |
13 40 | + | 2 5 | x | = | 11 40 | + | ( | 1 | − | x | ) | × | 2 5 |
| Right side of the equation = | 11 40 | + | 1 | × | 2 5 | − | x | × | 2 5 |
| = | 11 40 | + | 2 5 | − | x | × | 2 5 |
| = | 27 40 | − | 2 5 | x |
13 40 | + | 2 5 | x | = | 27 40 | − | 2 5 | x |
2 5 | x | + | 2 5 | x | = | 27 40 | − | 13 40 |
