| ( | 11 | + | 2 | x | ) | × | 3 10 | = | 30 | + | 17 10 | x |
| Left side of the equation = | 11 | × | 3 10 | + | 2 | x | × | 3 10 |
| = | 33 10 | + | 3 5 | x |
33 10 | + | 3 5 | x | = | 30 | + | 17 10 | x |
3 5 | x | − | 17 10 | x | = | 30 | − | 33 10 |
| - | 11 10 | x | = | 30 | − | 33 10 |
| - | 11 10 | x | = | 267 10 |
| - | 267 10 | = | 11 10 | x |
11 10 | x | = | - | 267 10 |
| x | = | - | 267 10 | ÷ | 11 10 |
| = | - | 267 10 | × | 10 11 |
| = | - | 267 | × | 1 11 |
| x | = | - | 267 11 |
| x | = | - 24.272727 |
