Work: Find the solution of equation （10-X）/(10-15) = 8300/12210 .
Question type: Equation
Solution:Original question:
| ( | 10 | − | X | ) | ÷ | ( | 10 | − | 15 | ) | = | 8300 | ÷ | 12210 |
| Multiply both sides of the equation by: | ( | 10 | − | 15 | ) |
| ( | 10 | − | X | ) | = | 8300 | ÷ | 12210 | × | ( | 10 | − | 15 | ) |
| 10 | − | X | = | 8300 | ÷ | 12210 | × | ( | 10 | − | 15 | ) |
| 10 | − | X | = | 8300 | ÷ | 12210 | × | 10 | − | 8300 | ÷ | 12210 | × | 15 |
| 10 | − | X | = | 8300 1221 | − | 4150 407 |
| 10 | − | X | = | - | 4150 1221 |
Transposition :
| - | X | = | - | 4150 1221 | − | 10 |
Combine the items on the right of the equation:
| - | X | = | - | 16360 1221 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
16360 1221 | = | 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 :
| X | = | 16360 1221 |
This is the solution of the equation.
