Work: Find the solution of equation （8973+48.44+X）*3.1% = 4X .
Question type: Equation
Solution:Original question:
| ( | 8973 | + | 1211 25 | + | X | ) | × | 31 1000 | = | 4 | X |
| Left side of the equation = | 8973 | × | 31 1000 | + | 1211 25 | × | 31 1000 | + | X | × | 31 1000 |
| = | 278163 1000 | + | 37541 25000 | + | X | × | 31 1000 |
| = | 873952 3125 | + | 31 1000 | X |
873952 3125 | + | 31 1000 | X | = | 4 | X |
Transposition :
31 1000 | X | − | 4 | X | = | - | 873952 3125 |
Combine the items on the left of the equation:
| - | 3969 1000 | X | = | - | 873952 3125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
873952 3125 | = | 3969 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 :
3969 1000 | X | = | 873952 3125 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 873952 3125 | ÷ | 3969 1000 |
| = | 873952 3125 | × | 1000 3969 |
| = | 873952 25 | × | 8 3969 |
We obtained :
| X | = | 6991616 99225 |
Convert the result to decimal form :
| X | = | 70.462242 |
