| X | + | 3 2 | ( | 65 | ÷ | 20 | ) | X | + | 5 2 | ( | 65 | ÷ | 15 | ) | X | = | 304 |
| Left side of the equation = | X | + | 3 2 | × | 65 | ÷ | 20 | × | X | + | 5 2 | ( | 65 | ÷ | 15 | ) | X |
| = | X | + | 39 8 | X | + | 5 2 | ( | 65 | ÷ | 15 | ) | X |
| = | 47 8 | X | + | 5 2 | ( | 65 | ÷ | 15 | ) | X |
| = | 47 8 | X | + | 5 2 | × | 65 | ÷ | 15 | × | X |
| = | 47 8 | X | + | 65 6 | X |
| = | 401 24 | X |
401 24 | X | = | 304 |
| X | = | 304 | ÷ | 401 24 |
| = | 304 | × | 24 401 |
| X | = | 7296 401 |
| X | = | 18.194514 |
