Work: Find the solution of equation （138057.03X-231128.61-1242.51X）/（231128.61+1242.51X） = 20% .
Question type: Equation
Solution:Original question:
| ( | 13805703 100 | X | − | 23112861 100 | − | 124251 100 | X | ) | ÷ | ( | 23112861 100 | + | 124251 100 | X | ) | = | 20 100 |
| Multiply both sides of the equation by: | ( | 23112861 100 | + | 124251 100 | X | ) |
| ( | 13805703 100 | X | − | 23112861 100 | − | 124251 100 | X | ) | = | 20 100 | ( | 23112861 100 | + | 124251 100 | X | ) |
13805703 100 | X | − | 23112861 100 | − | 124251 100 | X | = | 20 100 | ( | 23112861 100 | + | 124251 100 | X | ) |
13805703 100 | X | − | 23112861 100 | − | 124251 100 | X | = | 20 100 | × | 23112861 100 | + | 20 100 | × | 124251 100 | X |
13805703 100 | X | − | 23112861 100 | − | 124251 100 | X | = | 23112861 500 | + | 124251 500 | X |
3420363 25 | X | − | 23112861 100 | = | 23112861 500 | + | 124251 500 | X |
Transposition :
3420363 25 | X | − | 124251 500 | X | = | 23112861 500 | + | 23112861 100 |
Combine the items on the left of the equation:
68283009 500 | X | = | 23112861 500 | + | 23112861 100 |
The solution of the equation:
X1≈-186.017505 , keep 6 decimal places
X2≈2.030918 , keep 6 decimal places
There are 2 solution(s).
