Work: Find the solution of equation （54223-2.5X）*10.8/21.8*0.9 = 14494+9X .
Question type: Equation
Solution:Original question:
| ( | 54223 | − | 5 2 | X | ) | × | 54 5 | ÷ | 109 5 | × | 9 10 | = | 14494 | + | 9 | X |
| Left side of the equation = | ( | 54223 | − | 5 2 | X | ) | × | 243 545 |
| ( | 54223 | − | 5 2 | X | ) | × | 243 545 | = | 14494 | + | 9 | X |
| Left side of the equation = | 54223 | × | 243 545 | − | 5 2 | X | × | 243 545 |
| = | 13176189 545 | − | 243 218 | X |
13176189 545 | − | 243 218 | X | = | 14494 | + | 9 | X |
Transposition :
| - | 243 218 | X | − | 9 | X | = | 14494 | − | 13176189 545 |
Combine the items on the left of the equation:
| - | 2205 218 | X | = | 14494 | − | 13176189 545 |
Combine the items on the right of the equation:
| - | 2205 218 | X | = | - | 5276959 545 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5276959 545 | = | 2205 218 | 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 :
2205 218 | X | = | 5276959 545 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 5276959 545 | ÷ | 2205 218 |
| = | 5276959 545 | × | 218 2205 |
We obtained :
| X | = | 1150377062 1201725 |
By reducing fraction, we can get:
| X | = | 10553918 11025 |
Convert the result to decimal form :
| X | = | 957.271474 |
