[ 1/1 Equation]
Work: Find the solution of equation 1400x-(1400x/1.13*0.13-50x)*1.1-400*10000-550x = 0 .
Question type: Equation
Solution:Original question:
| 1400 | x | − | ( | 1400 | x | ÷ | 113 100 | × | 13 100 | − | 50 | x | ) | × | 11 10 | − | 400 | × | 10000 | − | 550 | x | = | 0 |
| Left side of the equation = | 1400 | x | − | ( | 1400 | x | ÷ | 113 100 | × | 13 100 | − | 50 | x | ) | × | 11 10 | − | 4000000 | − | 550 | x |
| = | 850 | x | − | ( | 1400 | x | ÷ | 113 100 | × | 13 100 | − | 50 | x | ) | × | 11 10 | − | 4000000 |
| 850 | x | − | ( | 1400 | x | ÷ | 113 100 | × | 13 100 | − | 50 | x | ) | × | 11 10 | − | 4000000 | = | 0 |
| Left side of the equation = | 850 | x | − | 1400 | x | ÷ | 113 100 | × | 13 100 | × | 11 10 | + | 50 | x | × | 11 10 | − | 4000000 |
| = | 850 | x | − | 20020 113 | x | + | 55 | x | − | 4000000 |
| = | 82245 113 | x | − | 4000000 |
82245 113 | x | − | 4000000 | = | 0 |
Transposition :
82245 113 | x | = | 0 | + | 4000000 |
Combine the items on the right of the equation:
82245 113 | x | = | 4000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4000000 | ÷ | 82245 113 |
| = | 4000000 | × | 113 82245 |
| = | 800000 | × | 113 16449 |
We obtained :
| x | = | 90400000 16449 |
Convert the result to decimal form :
| x | = | 5495.774819 |
