Work: Find the solution of equation 500-50➗4000-x = 800➗4000 .
Question type: Equation
Solution:Original question:
| 500 | − | 50 | ÷ | 4000 | − | x | = | 800 | ÷ | 4000 |
| Left side of the equation = | 500 | − | 1 80 | − | x |
| = | 39999 80 | − | x |
39999 80 | − | x | = | 800 | ÷ | 4000 |
| Right side of the equation = | 1 5 |
39999 80 | − | x | = | 1 5 |
Transposition :
| - | x | = | 1 5 | − | 39999 80 |
Combine the items on the right of the equation:
| - | x | = | - | 39983 80 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
39983 80 | = | 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 | = | 39983 80 |
This is the solution of the equation.
