Work: Find the solution of equation 0.087x÷54＋0.0299(1-x)÷65 = 0.000985 .
Question type: Equation
Solution:Original question:
87 1000 | x | ÷ | 54 | + | 299 10000 | ( | 1 | − | x | ) | ÷ | 65 | = | 197 200000 |
| Left side of the equation = | 29 18000 | x | + | 23 50000 | ( | 1 | − | x | ) |
29 18000 | x | + | 23 50000 | ( | 1 | − | x | ) | = | 197 200000 |
| Left side of the equation = | 29 18000 | x | + | 23 50000 | × | 1 | − | 23 50000 | x |
| = | 29 18000 | x | + | 23 50000 | − | 23 50000 | x |
| = | 259 225000 | x | + | 23 50000 |
259 225000 | x | + | 23 50000 | = | 197 200000 |
Transposition :
259 225000 | x | = | 197 200000 | − | 23 50000 |
Combine the items on the right of the equation:
259 225000 | x | = | 21 40000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 21 40000 | ÷ | 259 225000 |
| = | 21 40000 | × | 225000 259 |
| = | 3 8 | × | 45 37 |
We obtained :
| x | = | 135 296 |
Convert the result to decimal form :
| x | = | 0.456081 |
