| ( | x | − | 8 | ) | ÷ | 30 | = | ( | 10 | − | x | ) | ÷ | 360 |
| Left side of the equation = | x | × | 1 30 | − | 8 | × | 1 30 |
| = | x | × | 1 30 | − | 4 15 |
1 30 | x | − | 4 15 | = | ( | 10 | − | x | ) | ÷ | 360 |
| Right side of the equation = | 10 | × | 1 360 | − | x | × | 1 360 |
| = | 1 36 | − | x | × | 1 360 |
1 30 | x | − | 4 15 | = | 1 36 | − | 1 360 | x |
1 30 | x | + | 1 360 | x | = | 1 36 | + | 4 15 |
13 360 | x | = | 1 36 | + | 4 15 |
13 360 | x | = | 53 180 |
| x | = | 53 180 | ÷ | 13 360 |
| = | 53 180 | × | 360 13 |
| = | 53 | × | 2 13 |
| x | = | 106 13 |
| x | = | 8.153846 |
