| x | ÷ | ( | x | + | 828331 200 | ) | = | 1 4 |
| 方程两边同时乘以: | ( | x | + | 828331 200 | ) |
| x | = | 1 4 | ( | x | + | 828331 200 | ) |
| x | = | 1 4 | x | + | 1 4 | × | 828331 200 |
| x | = | 1 4 | x | + | 828331 800 |
| x | − | 1 4 | x | = | 828331 800 |
3 4 | x | = | 828331 800 |
| x | = | 828331 800 | ÷ | 3 4 |
| = | 828331 800 | × | 4 3 |
| = | 828331 200 | × | 1 3 |
| x | = | 828331 600 |
| x | = | 1380.551667 |
