| ( | 339 100 | − | 72 25 | ) | + | ( | 119 50 | − | 19 10 | ) | = | ( | 72 25 | − | 119 50 | ) | + | ( | 19 10 | − | x | ) |
| Left side of the equation = | 339 100 | − | 72 25 | + | ( | 119 50 | − | 19 10 | ) |
| = | 51 100 | + | ( | 119 50 | − | 19 10 | ) |
| = | 51 100 | + | 119 50 | − | 19 10 |
| = | 99 100 |
99 100 | = | ( | 72 25 | − | 119 50 | ) | + | ( | 19 10 | − | x | ) |
| Right side of the equation = | 72 25 | − | 119 50 | + | ( | 19 10 | − | x | ) |
| = | 1 2 | + | ( | 19 10 | − | x | ) |
| = | 1 2 | + | 19 10 | − | x |
| = | 12 5 | − | x |
