Work: Find the solution of equation （4173442.74-x-2000000）*0.15+450000 = x .
Question type: Equation
Solution:Original question:
| ( | 208672137 50 | − | x | − | 2000000 | ) | × | 3 20 | + | 450000 | = | x |
| Left side of the equation = | 208672137 50 | × | 3 20 | − | x | × | 3 20 | − | 2000000 | × | 3 20 | + | 450000 |
| = | 626016411 1000 | − | x | × | 3 20 | − | 300000 | + | 450000 |
| = | 776016411 1000 | − | 3 20 | x |
776016411 1000 | − | 3 20 | x | = | x |
Transposition :
| - | 3 20 | x | − | x | = | - | 776016411 1000 |
Combine the items on the left of the equation:
| - | 23 20 | x | = | - | 776016411 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
776016411 1000 | = | 23 20 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
23 20 | x | = | 776016411 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 776016411 1000 | ÷ | 23 20 |
| = | 776016411 1000 | × | 20 23 |
| = | 776016411 50 | × | 1 23 |
We obtained :
| x | = | 776016411 1150 |
Convert the result to decimal form :
| x | = | 674796.87913 |
