Work: Find the solution of equation （X-8.2）*2.1643 = 21.943 .
Question type: Equation
Solution:Original question:
| ( | X | − | 41 5 | ) | × | 21643 10000 | = | 21943 1000 |
| Left side of the equation = | X | × | 21643 10000 | − | 41 5 | × | 21643 10000 |
| = | X | × | 21643 10000 | − | 887363 50000 |
21643 10000 | X | − | 887363 50000 | = | 21943 1000 |
Transposition :
21643 10000 | X | = | 21943 1000 | + | 887363 50000 |
Combine the items on the right of the equation:
21643 10000 | X | = | 1984513 50000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1984513 50000 | ÷ | 21643 10000 |
| = | 1984513 50000 | × | 10000 21643 |
| = | 1984513 5 | × | 1 21643 |
We obtained :
| X | = | 1984513 108215 |
Convert the result to decimal form :
| X | = | 18.338613 |
