Work: Find the solution of equation 1400X/1.13-9000000-(1400X/1.13*0.13-500000)*0.1 = 0 .
Question type: Equation
Solution:Original question:
| 1400 | X | ÷ | 113 100 | − | 9000000 | − | ( | 1400 | X | ÷ | 113 100 | × | 13 100 | − | 500000 | ) | × | 1 10 | = | 0 |
| Left side of the equation = | 140000 113 | X | − | 9000000 | − | ( | 1400 | X | ÷ | 113 100 | × | 13 100 | − | 500000 | ) | × | 1 10 |
140000 113 | X | − | 9000000 | − | ( | 1400 | X | ÷ | 113 100 | × | 13 100 | − | 500000 | ) | × | 1 10 | = | 0 |
| Left side of the equation = | 140000 113 | X | − | 9000000 | − | 1400 | X | ÷ | 113 100 | × | 13 100 | × | 1 10 | + | 500000 | × | 1 10 |
| = | 140000 113 | X | − | 9000000 | − | 1820 113 | X | + | 50000 |
| = | 138180 113 | X | − | 8950000 |
138180 113 | X | − | 8950000 | = | 0 |
Transposition :
138180 113 | X | = | 0 | + | 8950000 |
Combine the items on the right of the equation:
138180 113 | X | = | 8950000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 8950000 | ÷ | 138180 113 |
| = | 8950000 | × | 113 138180 |
| = | 447500 | × | 113 6909 |
We obtained :
| X | = | 50567500 6909 |
Convert the result to decimal form :
| X | = | 7319.076567 |
