| 70 | = | x | − | x | ÷ | 113 100 | × | 1 20 | + | 4 |
| Right side of the equation = | x | − | x | × | 5 113 | + | 4 |
| = | 108 113 | x | + | 4 |
| 70 | = | 108 113 | x | + | 4 |
| - | 108 113 | x | = | 4 | − | 70 |
| - | 108 113 | x | = | - | 66 |
| 66 | = | 108 113 | x |
108 113 | x | = | 66 |
| x | = | 66 | ÷ | 108 113 |
| = | 66 | × | 113 108 |
| = | 11 | × | 113 18 |
| x | = | 1243 18 |
| x | = | 69.055556 |
