| ( | 8150 | + | 50 | + | X | ) | × | 33 1000 | = | 4 | X |
| Left side of the equation = | 8150 | × | 33 1000 | + | 50 | × | 33 1000 | + | X | × | 33 1000 |
| = | 5379 20 | + | 33 20 | + | X | × | 33 1000 |
| = | 1353 5 | + | 33 1000 | X |
1353 5 | + | 33 1000 | X | = | 4 | X |
33 1000 | X | − | 4 | X | = | - | 1353 5 |
| - | 3967 1000 | X | = | - | 1353 5 |
1353 5 | = | 3967 1000 | X |
3967 1000 | X | = | 1353 5 |
| X | = | 1353 5 | ÷ | 3967 1000 |
| = | 1353 5 | × | 1000 3967 |
| = | 1353 | × | 200 3967 |
| X | = | 270600 3967 |
| X | = | 68.212755 |
