Work: Find the solution of equation 850000-[850000/1.06*0.06-(x/1.06*0.06)]*0.12 = x .
Question type: Equation
Solution:Original question:
| 850000 | − | ( | 850000 | ÷ | 53 50 | × | 3 50 | − | ( | x | ÷ | 53 50 | × | 3 50 | ) | ) | × | 3 25 | = | x |
| Left side of the equation = | 850000 | − | 850000 | ÷ | 53 50 | × | 3 50 | × | 3 25 | + | ( | x | ÷ | 53 50 | × | 3 50 | ) | × | 3 25 |
| = | 850000 | − | 306000 53 | + | ( | x | ÷ | 53 50 | × | 3 50 | ) | × | 3 25 |
| = | 44744000 53 | + | ( | x | ÷ | 53 50 | × | 3 50 | ) | × | 3 25 |
| = | 44744000 53 | + | x | ÷ | 53 50 | × | 3 50 | × | 3 25 |
| = | 44744000 53 | + | x | × | 9 1325 |
44744000 53 | + | 9 1325 | x | = | x |
Transposition :
9 1325 | x | − | x | = | - | 44744000 53 |
Combine the items on the left of the equation:
| - | 1316 1325 | x | = | - | 44744000 53 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
44744000 53 | = | 1316 1325 | 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 :
1316 1325 | x | = | 44744000 53 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 44744000 53 | ÷ | 1316 1325 |
| = | 44744000 53 | × | 1325 1316 |
| = | 34000 | × | 25 |
We obtained :
| x | = | 850000 |
