[ 2/3 Equation]
Work: Find the solution of equation -x+4+4 = x-3 .
Question type: Equation
Solution:Original question:
| - | x | + | 4 | + | 4 | = | x | − | 3 |
| Left side of the equation = | - | x | + | 8 |
| - | x | + | 8 | = | x | − | 3 |
Transposition :
| - | x | − | x | = | - | 3 | − | 8 |
Combine the items on the left of the equation:
| - | 2 | x | = | - | 3 | − | 8 |
Combine the items on the right of the equation:
| - | 2 | x | = | - | 11 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 11 | = | 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 | = | 11 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11 | ÷ | 2 |
| = | 11 | × | 1 2 |
We obtained :
| x | = | 11 2 |
Convert the result to decimal form :
| x | = | 5.5 |
