Work: Find the solution of equation x+(148807.44-x)*0.001*23 = 5000 .
Question type: Equation
Solution:Original question:
| x | + | ( | 3720186 25 | − | x | ) | × | 1 1000 | × | 23 | = | 5000 |
| Left side of the equation = | x | + | ( | 3720186 25 | − | x | ) | × | 23 1000 |
| x | + | ( | 3720186 25 | − | x | ) | × | 23 1000 | = | 5000 |
| Left side of the equation = | x | + | 3720186 25 | × | 23 1000 | − | x | × | 23 1000 |
| = | x | + | 42782139 12500 | − | x | × | 23 1000 |
| = | 977 1000 | x | + | 42782139 12500 |
977 1000 | x | + | 42782139 12500 | = | 5000 |
Transposition :
977 1000 | x | = | 5000 | − | 42782139 12500 |
Combine the items on the right of the equation:
977 1000 | x | = | 19717861 12500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 19717861 12500 | ÷ | 977 1000 |
| = | 19717861 12500 | × | 1000 977 |
| = | 19717861 25 | × | 2 977 |
We obtained :
| x | = | 39435722 24425 |
Convert the result to decimal form :
| x | = | 1614.563849 |
