| = | 3 4 | x | + | 10 | ( | 1 | − | 1 | ÷ | 4 | ) | + | ( | 1 | − | 1 | ÷ | 6 | ) | x |
| = | 3 4 | x | + | 10 | × | 1 | − | 10 | × | 1 | ÷ | 4 | + | ( | 1 | − | 1 | ÷ | 6 | ) | x |
| = | 3 4 | x | + | 10 | − | 5 2 | + | ( | 1 | − | 1 | ÷ | 6 | ) | x |
| = | 3 4 | x | + | 15 2 | + | ( | 1 | − | 1 | ÷ | 6 | ) | x |
| = | 3 4 | x | + | 15 2 | + | 1 | x | − | 1 | ÷ | 6 | × | x |
| = | 3 4 | x | + | 15 2 | + | 1 | x | − | 1 6 | x |
| = | 19 12 | x | + | 15 2 |
19 12 | x | + | 15 2 | = | 150 |
19 12 | x | = | 150 | − | 15 2 |
19 12 | x | = | 285 2 |
| x | = | 285 2 | ÷ | 19 12 |
