Work: Find the solution of equation （70722-2.5X）*15.2/26.1*0.9 = 19459+10X .
Question type: Equation
Solution:Original question:
| ( | 70722 | − | 5 2 | X | ) | × | 76 5 | ÷ | 261 10 | × | 9 10 | = | 19459 | + | 10 | X |
| Left side of the equation = | ( | 70722 | − | 5 2 | X | ) | × | 76 145 |
| ( | 70722 | − | 5 2 | X | ) | × | 76 145 | = | 19459 | + | 10 | X |
| Left side of the equation = | 70722 | × | 76 145 | − | 5 2 | X | × | 76 145 |
| = | 5374872 145 | − | 38 29 | X |
5374872 145 | − | 38 29 | X | = | 19459 | + | 10 | X |
Transposition :
| - | 38 29 | X | − | 10 | X | = | 19459 | − | 5374872 145 |
Combine the items on the left of the equation:
| - | 328 29 | X | = | 19459 | − | 5374872 145 |
Combine the items on the right of the equation:
| - | 328 29 | X | = | - | 2553317 145 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2553317 145 | = | 328 29 | 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 :
328 29 | X | = | 2553317 145 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2553317 145 | ÷ | 328 29 |
| = | 2553317 145 | × | 29 328 |
| = | 2553317 5 | × | 1 328 |
We obtained :
| X | = | 2553317 1640 |
Convert the result to decimal form :
| X | = | 1556.90061 |
