Work: Find the solution of equation （360-x）/（396-x） = 610/1235 .
Question type: Equation
Solution:Original question:
| ( | 360 | − | x | ) | ÷ | ( | 396 | − | x | ) | = | 610 | ÷ | 1235 |
| Multiply both sides of the equation by: | ( | 396 | − | x | ) |
| ( | 360 | − | x | ) | = | 610 | ÷ | 1235 | × | ( | 396 | − | x | ) |
| 360 | − | x | = | 610 | ÷ | 1235 | × | ( | 396 | − | x | ) |
| 360 | − | x | = | 610 | ÷ | 1235 | × | 396 | − | 610 | ÷ | 1235 | × | x |
| 360 | − | x | = | 48312 247 | − | 122 247 | x |
Transposition :
| - | x | + | 122 247 | x | = | 48312 247 | − | 360 |
Combine the items on the left of the equation:
| - | 125 247 | x | = | 48312 247 | − | 360 |
Combine the items on the right of the equation:
| - | 125 247 | x | = | - | 40608 247 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
40608 247 | = | 125 247 | 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 :
125 247 | x | = | 40608 247 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 40608 247 | ÷ | 125 247 |
| = | 40608 247 | × | 247 125 |
| = | 40608 | × | 1 125 |
We obtained :
| x | = | 40608 125 |
Convert the result to decimal form :
| x | = | 324.864 |
