| 4 | x | = | 7 2 | + | 7 | ( | 7 4 | ÷ | 100000 | × | x | ) | ( | 1 | ÷ | 2 | ) |
| Right side of the equation = | 7 2 | + | 7 | × | 7 4 | ÷ | 100000 | × | x | ( | 1 | ÷ | 2 | ) |
| = | 7 2 | + | 49 400000 | x | ( | 1 | ÷ | 2 | ) |
| = | 7 2 | + | 49 400000 | x | × | 1 | ÷ | 2 |
| = | 7 2 | + | 49 800000 | x |
| 4 | x | = | 7 2 | + | 49 800000 | x |
| 4 | x | − | 49 800000 | x | = | 7 2 |
3199951 800000 | x | = | 7 2 |
| x | = | 7 2 | ÷ | 3199951 800000 |
| = | 7 2 | × | 800000 3199951 |
| = | 7 | × | 400000 3199951 |
| x | = | 2800000 3199951 |
| x | = | 0.875013 |
