Work: Find the solution of equation （X-0.0040）*0.343*100/0.5000 = 0.31 .
Question type: Equation
Solution:Original question:
| ( | X | − | 1 250 | ) | × | 343 1000 | × | 100 | ÷ | 1 2 | = | 31 100 |
| Left side of the equation = | ( | X | − | 1 250 | ) | × | 343 5 |
| ( | X | − | 1 250 | ) | × | 343 5 | = | 31 100 |
| Left side of the equation = | X | × | 343 5 | − | 1 250 | × | 343 5 |
| = | X | × | 343 5 | − | 343 1250 |
343 5 | X | − | 343 1250 | = | 31 100 |
Transposition :
343 5 | X | = | 31 100 | + | 343 1250 |
Combine the items on the right of the equation:
343 5 | X | = | 1461 2500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1461 2500 | ÷ | 343 5 |
| = | 1461 2500 | × | 5 343 |
| = | 1461 500 | × | 1 343 |
We obtained :
| X | = | 1461 171500 |
Convert the result to decimal form :
| X | = | 0.008519 |
