2 5 | ( | 10 | + | x | ) | = | 1 5 | ( | 8 | + | 2 | x | ) |
| Left side of the equation = | 2 5 | × | 10 | + | 2 5 | x |
| = | 4 | + | 2 5 | x |
| 4 | + | 2 5 | x | = | 1 5 | ( | 8 | + | 2 | x | ) |
| Right side of the equation = | 1 5 | × | 8 | + | 1 5 | × | 2 | x |
| = | 8 5 | + | 2 5 | x |
| 4 | + | 2 5 | x | = | 8 5 | + | 2 5 | x |
2 5 | x | − | 2 5 | x | = | 8 5 | − | 4 |
| 0 | x | = | 8 5 | − | 4 |
| 0 | x | = | - | 12 5 |
