| - | 144 | + | 8 | x | + | 36 | × | 36 | − | 288 | x | + | 4 | x | = | 0 |
| Left side of the equation = | - | 144 | + | 8 | x | + | 1296 | − | 288 | x | + | 4 | x |
| = | 1152 | − | 276 | x |
| 1152 | − | 276 | x | = | 0 |
| - | 276 | x | = | 0 | − | 1152 |
| - | 276 | x | = | - | 1152 |
| 1152 | = | 276 | x |
| 276 | x | = | 1152 |
| x | = | 1152 | ÷ | 276 |
| = | 1152 | × | 1 276 |
| = | 96 | × | 1 23 |
| x | = | 96 23 |
| x | = | 4.173913 |
