[ 1/1 Equation]
Work: Find the solution of equation （x-43.8）/43.8+x*0.13+（x-43.8)*0.05 = 0.09 .
Question type: Equation
Solution:Original question:
| ( | x | − | 219 5 | ) | ÷ | 219 5 | + | x | × | 13 100 | + | ( | x | − | 219 5 | ) | × | 1 20 | = | 9 100 |
| Left side of the equation = | x | × | 5 219 | − | 219 5 | × | 5 219 | + | 13 100 | x | + | ( | x | − | 219 5 | ) | × | 1 20 |
| = | x | × | 5 219 | − | 1 | + | 13 100 | x | + | ( | x | − | 219 5 | ) | × | 1 20 |
| = | 3347 21900 | x | − | 1 | + | ( | x | − | 219 5 | ) | × | 1 20 |
| = | 3347 21900 | x | − | 1 | + | x | × | 1 20 | − | 219 5 | × | 1 20 |
| = | 3347 21900 | x | − | 1 | + | x | × | 1 20 | − | 219 100 |
| = | 2221 10950 | x | − | 319 100 |
2221 10950 | x | − | 319 100 | = | 9 100 |
Transposition :
2221 10950 | x | = | 9 100 | + | 319 100 |
Combine the items on the right of the equation:
2221 10950 | x | = | 82 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 82 25 | ÷ | 2221 10950 |
| = | 82 25 | × | 10950 2221 |
| = | 82 | × | 438 2221 |
We obtained :
| x | = | 35916 2221 |
Convert the result to decimal form :
| x | = | 16.171094 |
