Work: Find the solution of equation 25684.96-20208-7138.68-x+20208-7138.68-x+x+7138.68 = 25684.96 .
Question type: Equation
Solution:Original question:
642124 25 | − | 20208 | − | 178467 25 | − | x | + | 20208 | − | 178467 25 | − | x | + | x | + | 178467 25 | = | 642124 25 |
| Left side of the equation = | 463657 25 | − | 1 | x |
463657 25 | − | 1 | x | = | 642124 25 |
Transposition :
| - | 1 | x | = | 642124 25 | − | 463657 25 |
| - | x | = | 642124 25 | − | 463657 25 |
Combine the items on the right of the equation:
| - | x | = | 178467 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 178467 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 :
| x | = | - | 178467 25 |
This is the solution of the equation.
