| x | + | ( | x | × | 1 10 | ) | + | ( | x | + | x | × | 1 10 | ) | × | 3 50 | = | 358 |
| Left side of the equation = | x | + | x | × | 1 10 | + | ( | x | + | x | × | 1 10 | ) | × | 3 50 |
| = | 11 10 | x | + | ( | x | + | x | × | 1 10 | ) | × | 3 50 |
| = | 11 10 | x | + | x | × | 3 50 | + | x | × | 1 10 | × | 3 50 |
| = | 11 10 | x | + | x | × | 3 50 | + | x | × | 3 500 |
| = | 583 500 | x |
583 500 | x | = | 358 |
| x | = | 358 | ÷ | 583 500 |
| = | 358 | × | 500 583 |
| x | = | 179000 583 |
| x | = | 307.03259 |
