Work: Find the solution of equation （8973+48.44+X）*3.5% = 4X .
Question type: Equation
Solution:Original question:
| ( | 8973 | + | 1211 25 | + | X | ) | × | 7 200 | = | 4 | X |
| Left side of the equation = | 8973 | × | 7 200 | + | 1211 25 | × | 7 200 | + | X | × | 7 200 |
| = | 62811 200 | + | 8477 5000 | + | X | × | 7 200 |
| = | 197344 625 | + | 7 200 | X |
197344 625 | + | 7 200 | X | = | 4 | X |
Transposition :
7 200 | X | − | 4 | X | = | - | 197344 625 |
Combine the items on the left of the equation:
| - | 793 200 | X | = | - | 197344 625 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
197344 625 | = | 793 200 | 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 :
793 200 | X | = | 197344 625 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 197344 625 | ÷ | 793 200 |
| = | 197344 625 | × | 200 793 |
| = | 197344 25 | × | 8 793 |
We obtained :
| X | = | 1578752 19825 |
Convert the result to decimal form :
| X | = | 79.634401 |
