Work: Find the solution of equation （22.12*（1+15%））+（3%*x） = x .
Question type: Equation
Solution:Original question:
| ( | 553 25 | ( | 1 | + | 15 100 | ) | ) | + | ( | 3 100 | x | ) | = | x |
| Left side of the equation = | 553 25 | ( | 1 | + | 15 100 | ) | + | ( | 3 100 | x | ) |
| = | 553 25 | × | 1 | + | 553 25 | × | 15 100 | + | ( | 3 100 | x | ) |
| = | 553 25 | + | 1659 500 | + | ( | 3 100 | x | ) |
| = | 12719 500 | + | ( | 3 100 | x | ) |
| = | 12719 500 | + | 3 100 | x |
12719 500 | + | 3 100 | x | = | x |
Transposition :
3 100 | x | − | x | = | - | 12719 500 |
Combine the items on the left of the equation:
| - | 97 100 | x | = | - | 12719 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
12719 500 | = | 97 100 | 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 :
97 100 | x | = | 12719 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12719 500 | ÷ | 97 100 |
| = | 12719 500 | × | 100 97 |
| = | 12719 5 | × | 1 97 |
We obtained :
| x | = | 12719 485 |
Convert the result to decimal form :
| x | = | 26.224742 |
