[ 1/1 Equation]
Work: Find the solution of equation 0.96x-200 = x-440 .
Question type: Equation
Solution:Original question:
24 25 | x | − | 200 | = | x | − | 440 |
Transposition :
24 25 | x | − | x | = | - | 440 | + | 200 |
Combine the items on the left of the equation:
| - | 1 25 | x | = | - | 440 | + | 200 |
Combine the items on the right of the equation:
| - | 1 25 | x | = | - | 240 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 240 | = | 1 25 | 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 :
1 25 | x | = | 240 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 240 | ÷ | 1 25 |
| = | 240 | × | 25 |
We obtained :
| x | = | 6000 |
