| ( | 5353 2 | + | 5353 100 | + | 1 100 | K | × | 1 | + | 6127 100 | ) | × | 5 100 | = | 0 |
| Left side of the equation = | 5353 2 | × | 5 100 | + | 5353 100 | × | 5 100 | + | 1 100 | K | × | 1 | × | 5 100 | + | 6127 100 | × | 5 100 |
| = | 5353 40 | + | 5353 2000 | + | 1 2000 | K | + | 6127 2000 |
| = | 27913 200 | + | 1 2000 | K |
27913 200 | + | 1 2000 | K | = | 0 |
1 2000 | K | = | 0 | − | 27913 200 |
1 2000 | K | = | - | 27913 200 |
| K | = | - | 27913 200 | ÷ | 1 2000 |
