Work: Find the solution of equation 2X+31.5-3X = 30 .
Question type: Equation
Solution:Original question:
| 2 | X | + | 63 2 | − | 3 | X | = | 30 |
| Left side of the equation = | - | 1 | X | + | 63 2 |
| - | 1 | X | + | 63 2 | = | 30 |
Transposition :
| - | 1 | X | = | 30 | − | 63 2 |
| - | X | = | 30 | − | 63 2 |
Combine the items on the right of the equation:
| - | X | = | - | 3 2 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3 2 | = | 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 | = | 3 2 |
This is the solution of the equation.
