[ 1/1 Equation]
Work: Find the solution of equation 100*（22.9989-x）/（22.9989-21.9986） = 0.25 .
Question type: Equation
Solution:Original question:
| 100 | ( | 229989 10000 | − | x | ) | ÷ | ( | 229989 10000 | − | 109993 5000 | ) | = | 1 4 |
| Multiply both sides of the equation by: | ( | 229989 10000 | − | 109993 5000 | ) |
| 100 | ( | 229989 10000 | − | x | ) | = | 1 4 | ( | 229989 10000 | − | 109993 5000 | ) |
| 100 | × | 229989 10000 | − | 100 | x | = | 1 4 | ( | 229989 10000 | − | 109993 5000 | ) |
| 100 | × | 229989 10000 | − | 100 | x | = | 1 4 | × | 229989 10000 | − | 1 4 | × | 109993 5000 |
229989 100 | − | 100 | x | = | 229989 40000 | − | 109993 20000 |
229989 100 | − | 100 | x | = | 10003 40000 |
Transposition :
| - | 100 | x | = | 10003 40000 | − | 229989 100 |
Combine the items on the right of the equation:
| - | 100 | x | = | - | 91985597 40000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
91985597 40000 | = | 100 | 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 :
| 100 | x | = | 91985597 40000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 91985597 40000 | ÷ | 100 |
| = | 91985597 40000 | × | 1 100 |
We obtained :
| x | = | 91985597 4000000 |
Convert the result to decimal form :
| x | = | 22.996399 |
