Work: Find the solution of equation 128➗(237+x) = 95％ .
Question type: Equation
Solution:Original question:
| 128 | ÷ | ( | 237 | + | x | ) | = | 95 100 |
| Multiply both sides of the equation by: | ( | 237 | + | x | ) |
| 128 | = | 95 100 | ( | 237 | + | x | ) |
| 128 | = | 95 100 | × | 237 | + | 95 100 | x |
| 128 | = | 4503 20 | + | 95 100 | x |
Transposition :
| - | 95 100 | x | = | 4503 20 | − | 128 |
Combine the items on the right of the equation:
| - | 95 100 | x | = | 1943 20 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 1943 20 | = | 95 100 | 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 :
95 100 | x | = | - | 1943 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1943 20 | ÷ | 95 100 |
| = | - | 1943 20 | × | 100 95 |
| = | - | 1943 | × | 5 95 |
We obtained :
| x | = | - | 9715 95 |
By reducing fraction, we can get:
| x | = | - | 1943 19 |
Convert the result to decimal form :
| x | = | - 102.263158 |
