Work: Find the solution of equation 2X-2 = 25-X .
Question type: Equation
Solution:Original question:
| 2 | X | − | 2 | = | 25 | − | X |
Transposition :
| 2 | X | + | X | = | 25 | + | 2 |
Combine the items on the left of the equation:
| 3 | X | = | 25 | + | 2 |
Combine the items on the right of the equation:
| 3 | X | = | 27 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 27 | ÷ | 3 |
| = | 27 | × | 1 3 |
| = | 9 | × | 1 |
We obtained :
| X | = | 9 |
