Work: Find the solution of equation 9% = （448542.86-X）/448542.86*100% .
Question type: Equation
Solution:Original question:
9 100 | = | ( | 22427143 50 | − | X | ) | ÷ | 22427143 50 | × | 100 100 |
| Right side of the equation = | ( | 22427143 50 | − | X | ) | × | 50 22427143 |
9 100 | = | ( | 22427143 50 | − | X | ) | × | 50 22427143 |
| Right side of the equation = | 22427143 50 | × | 50 22427143 | − | X | × | 50 22427143 |
| = | 1949 1949 | − | X | × | 50 22427143 |
9 100 | = | 1949 1949 | − | 50 22427143 | X |
Transposition :
50 22427143 | X | = | 1949 1949 | − | 9 100 |
Combine the items on the right of the equation:
50 22427143 | X | = | 177359 194900 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 177359 194900 | ÷ | 50 22427143 |
| = | 177359 194900 | × | 22427143 50 |
We obtained :
| X | = | 3977655655337 9745000 |
