☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation （24.2-x）/x*100% = 1.7% .
Question type: Equation
Solution:Original question:
| ( | 121 5 | − | x | ) | ÷ | x | × | 100 100 | = | 17 1000 |
| Multiply both sides of the equation by: | x |
| ( | 121 5 | − | x | ) | × | 100 100 | = | 17 1000 | x |
121 5 | × | 100 100 | − | x | × | 100 100 | = | 17 1000 | x |
121 5 | − | x | × | 100 100 | = | 17 1000 | x |
Transposition :
| - | 100 100 | x | − | 17 1000 | x | = | - | 121 5 |
Combine the items on the left of the equation:
| - | 1017 1000 | x | = | - | 121 5 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
121 5 | = | 1017 1000 | 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 :
1017 1000 | x | = | 121 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 121 5 | ÷ | 1017 1000 |
| = | 121 5 | × | 1000 1017 |
| = | 121 | × | 200 1017 |
We obtained :
| x | = | 24200 1017 |
Convert the result to decimal form :
| x | = | 23.795477 |
