[ 1/1 Equation]
Work: Find the solution of equation （1.0210—X）➗1.0210 = 15% .
Question type: Equation
Solution:Original question:
| ( | 1021 1000 | − | X | ) | ÷ | 1021 1000 | = | 15 100 |
| Left side of the equation = | 1021 1000 | × | 1000 1021 | − | X | × | 1000 1021 |
| = | 1021 1021 | − | X | × | 1000 1021 |
1021 1021 | − | 1000 1021 | X | = | 15 100 |
Transposition :
| - | 1000 1021 | X | = | 15 100 | − | 1021 1021 |
Combine the items on the right of the equation:
| - | 1000 1021 | X | = | - | 17357 20420 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
17357 20420 | = | 1000 1021 | 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 :
1000 1021 | X | = | 17357 20420 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 17357 20420 | ÷ | 1000 1021 |
| = | 17357 20420 | × | 1021 1000 |
We obtained :
| X | = | 17721497 20420000 |
By reducing fraction, we can get:
| X | = | 17357 20000 |
Convert the result to decimal form :
| X | = | 0.86785 |
