Work: Find the solution of equation 50减a加30 = 48 .
Question type: Equation
Solution:Original question:
| 50 | − | a | + | 30 | = | 48 |
| Left side of the equation = | 80 | − | a |
| 80 | − | a | = | 48 |
Transposition :
| - | a | = | 48 | − | 80 |
Combine the items on the right of the equation:
| - | a | = | - | 32 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 32 | = | a |
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 :
| a | = | 32 |
This is the solution of the equation.
