Work: Find the solution of equation 1400X/1.13-500X-4000000-(1400/1.13*0.13*X-50X)*1.1 = 0 .
Question type: Equation
Solution:Original question:
| 1400 | X | ÷ | 113 100 | − | 500 | X | − | 4000000 | − | ( | 1400 | ÷ | 113 100 | × | 13 100 | X | − | 50 | X | ) | × | 11 10 | = | 0 |
| Left side of the equation = | 140000 113 | X | − | 500 | X | − | 4000000 | − | ( | 1400 | ÷ | 113 100 | × | 13 100 | X | − | 50 | X | ) | × | 11 10 |
| = | 83500 113 | X | − | 4000000 | − | ( | 1400 | ÷ | 113 100 | × | 13 100 | X | − | 50 | X | ) | × | 11 10 |
83500 113 | X | − | 4000000 | − | ( | 1400 | ÷ | 113 100 | × | 13 100 | X | − | 50 | X | ) | × | 11 10 | = | 0 |
| Left side of the equation = | 83500 113 | X | − | 4000000 | − | 1400 | ÷ | 113 100 | × | 13 100 | X | × | 11 10 | + | 50 | X | × | 11 10 |
| = | 83500 113 | X | − | 4000000 | − | 20020 113 | X | + | 55 | X |
| = | 69695 113 | X | − | 4000000 |
69695 113 | X | − | 4000000 | = | 0 |
Transposition :
69695 113 | X | = | 0 | + | 4000000 |
Combine the items on the right of the equation:
69695 113 | X | = | 4000000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4000000 | ÷ | 69695 113 |
| = | 4000000 | × | 113 69695 |
| = | 800000 | × | 113 13939 |
We obtained :
| X | = | 90400000 13939 |
Convert the result to decimal form :
| X | = | 6485.400674 |
