| ( | 200 | − | 10 | x | ) | ( | 32 | + | 2 | ) | = | 0 |
| Left side of the equation = | 200 | ( | 32 | + | 2 | ) | − | 10 | x | ( | 32 | + | 2 | ) |
| = | 200 | × | 32 | + | 200 | × | 2 | − | 10 | x | ( | 32 | + | 2 | ) |
| = | 6400 | + | 400 | − | 10 | x | ( | 32 | + | 2 | ) |
| = | 6800 | − | 10 | x | ( | 32 | + | 2 | ) |
| = | 6800 | − | 10 | x | × | 32 | − | 10 | x | × | 2 |
| = | 6800 | − | 320 | x | − | 20 | x |
| = | 6800 | − | 340 | x |
| 6800 | − | 340 | x | = | 0 |
| - | 340 | x | = | 0 | − | 6800 |
| - | 340 | x | = | - | 6800 |
| 6800 | = | 340 | x |
| 340 | x | = | 6800 |
| x | = | 6800 | ÷ | 340 |
| = | 6800 | × | 1 340 |
| = | 20 | × | 1 |
| x | = | 20 |
