6 100 | + | 8 5 | ( | x | − | 6 100 | ) | = | 22 100 |
| Left side of the equation = | 6 100 | + | 8 5 | x | − | 8 5 | × | 6 100 |
| = | 6 100 | + | 8 5 | x | − | 12 125 |
| = | - | 9 250 | + | 8 5 | x |
| - | 9 250 | + | 8 5 | x | = | 22 100 |
8 5 | x | = | 22 100 | + | 9 250 |
8 5 | x | = | 32 125 |
| x | = | 32 125 | ÷ | 8 5 |
| = | 32 125 | × | 5 8 |
| = | 4 25 | × | 1 |
| x | = | 4 25 |
| x | = | 0.16 |
