[ 2/3 Equation]
Work: Find the solution of equation -X+4 = X-5 .
Question type: Equation
Solution:Original question:
| - | X | + | 4 | = | X | − | 5 |
Transposition :
| - | X | − | X | = | - | 5 | − | 4 |
Combine the items on the left of the equation:
| - | 2 | X | = | - | 5 | − | 4 |
Combine the items on the right of the equation:
| - | 2 | X | = | - | 9 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 9 | = | 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 :
| 2 | X | = | 9 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 9 | ÷ | 2 |
| = | 9 | × | 1 2 |
We obtained :
| X | = | 9 2 |
Convert the result to decimal form :
| X | = | 4.5 |
