[ 1/1 Equation]
Work: Find the solution of equation （81482-2.5X）*8.4/19.4*0.9 = 18130+7X .
Question type: Equation
Solution:Original question:
| ( | 81482 | − | 5 2 | X | ) | × | 42 5 | ÷ | 97 5 | × | 9 10 | = | 18130 | + | 7 | X |
| Left side of the equation = | ( | 81482 | − | 5 2 | X | ) | × | 189 485 |
| ( | 81482 | − | 5 2 | X | ) | × | 189 485 | = | 18130 | + | 7 | X |
| Left side of the equation = | 81482 | × | 189 485 | − | 5 2 | X | × | 189 485 |
| = | 15400098 485 | − | 189 194 | X |
15400098 485 | − | 189 194 | X | = | 18130 | + | 7 | X |
Transposition :
| - | 189 194 | X | − | 7 | X | = | 18130 | − | 15400098 485 |
Combine the items on the left of the equation:
| - | 1547 194 | X | = | 18130 | − | 15400098 485 |
Combine the items on the right of the equation:
| - | 1547 194 | X | = | - | 6607048 485 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
6607048 485 | = | 1547 194 | 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 :
1547 194 | X | = | 6607048 485 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 6607048 485 | ÷ | 1547 194 |
| = | 6607048 485 | × | 194 1547 |
| = | 943864 485 | × | 194 221 |
We obtained :
| X | = | 183109616 107185 |
By reducing fraction, we can get:
| X | = | 1887728 1105 |
Convert the result to decimal form :
| X | = | 1708.351131 |
