| ( | 70461 5 | + | 200000 | x | ) | × | 9 5 | = | 250000000 |
| Left side of the equation = | 70461 5 | × | 9 5 | + | 200000 | x | × | 9 5 |
| = | 634149 25 | + | 360000 | x |
634149 25 | + | 360000 | x | = | 250000000 |
| 360000 | x | = | 250000000 | − | 634149 25 |
| 360000 | x | = | 6249365851 25 |
| x | = | 6249365851 25 | ÷ | 360000 |
| = | 6249365851 25 | × | 1 360000 |
