Work: Find the solution of equation 9+（x-200）/300*11.9+0.15x+x = 473 .
Question type: Equation
Solution:Original question:
| 9 | + | ( | x | − | 200 | ) | ÷ | 300 | × | 119 10 | + | 3 20 | x | + | x | = | 473 |
| Left side of the equation = | 9 | + | ( | x | − | 200 | ) | × | 119 3000 | + | 3 20 | x | + | x |
| = | 9 | + | ( | x | − | 200 | ) | × | 119 3000 | + | 23 20 | x |
| 9 | + | ( | x | − | 200 | ) | × | 119 3000 | + | 23 20 | x | = | 473 |
| Left side of the equation = | 9 | + | x | × | 119 3000 | − | 200 | × | 119 3000 | + | 23 20 | x |
| = | 9 | + | x | × | 119 3000 | − | 119 15 | + | 23 20 | x |
| = | 16 15 | + | 3569 3000 | x |
16 15 | + | 3569 3000 | x | = | 473 |
Transposition :
3569 3000 | x | = | 473 | − | 16 15 |
Combine the items on the right of the equation:
3569 3000 | x | = | 7079 15 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7079 15 | ÷ | 3569 3000 |
| = | 7079 15 | × | 3000 3569 |
| = | 7079 | × | 200 3569 |
We obtained :
| x | = | 1415800 3569 |
Convert the result to decimal form :
| x | = | 396.693752 |
