| ( | 3 5 | + | x | ) | × | 1 5 | ÷ | 2 | = | 0 |
| Left side of the equation = | ( | 3 5 | + | x | ) | × | 1 10 |
| ( | 3 5 | + | x | ) | × | 1 10 | = | 0 |
| Left side of the equation = | 3 5 | × | 1 10 | + | x | × | 1 10 |
| = | 3 50 | + | x | × | 1 10 |
3 50 | + | 1 10 | x | = | 0 |
1 10 | x | = | 0 | − | 3 50 |
1 10 | x | = | - | 3 50 |
| x | = | - | 3 50 | ÷ | 1 10 |
| = | - | 3 50 | × | 10 |
| = | - | 3 5 | × | 1 |
