| ( | x | − | 13 5 | ) | ÷ | x | = | 31111 100000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 13 5 | ) | = | 31111 100000 | x |
| x | − | 13 5 | = | 31111 100000 | x |
| x | − | 31111 100000 | x | = | 13 5 |
68889 100000 | x | = | 13 5 |
| x | = | 13 5 | ÷ | 68889 100000 |
| = | 13 5 | × | 100000 68889 |
| = | 13 | × | 20000 68889 |
| x | = | 260000 68889 |
| x | = | 3.774187 |
