| ( | 15 | x | + | 186 | ) | ÷ | 3 | = | ( | 496 | − | 52 | x | ) | ÷ | 2 |
| Left side of the equation = | 15 | x | × | 1 3 | + | 186 | × | 1 3 |
| = | 5 | x | + | 62 |
| 5 | x | + | 62 | = | ( | 496 | − | 52 | x | ) | ÷ | 2 |
| Right side of the equation = | 496 | × | 1 2 | − | 52 | x | × | 1 2 |
| = | 248 | − | 26 | x |
| 5 | x | + | 62 | = | 248 | − | 26 | x |
| 5 | x | + | 26 | x | = | 248 | − | 62 |
| 31 | x | = | 248 | − | 62 |
| 31 | x | = | 186 |
| x | = | 186 | ÷ | 31 |
| = | 186 | × | 1 31 |
| = | 6 | × | 1 |
| x | = | 6 |
