☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation （X*1.13-0.42*1.13)/(X*1.13) = 0 .
Question type: Equation
Solution:Original question:
| ( | X | × | 113 100 | − | 21 50 | × | 113 100 | ) | ÷ | ( | X | × | 113 100 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | X | × | 113 100 | ) |
| ( | X | × | 113 100 | − | 21 50 | × | 113 100 | ) | = | 0 |
| X | × | 113 100 | − | 21 50 | × | 113 100 | = | 0 |
| X | × | 113 100 | − | 2373 5000 | = | 0 |
Transposition :
113 100 | X | = | 0 | + | 2373 5000 |
Combine the items on the right of the equation:
113 100 | X | = | 2373 5000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2373 5000 | ÷ | 113 100 |
| = | 2373 5000 | × | 100 113 |
| = | 2373 50 | × | 1 113 |
We obtained :
| X | = | 2373 5650 |
Convert the result to decimal form :
| X | = | 0.42 |
