Work: Find the solution of equation 4x－（6+x） = 18 .
Question type: Equation
Solution:Original question:
| 4 | x | − | ( | 6 | + | x | ) | = | 18 |
| Left side of the equation = | 4 | x | − | 6 | − | x |
| = | 3 | x | − | 6 |
| 3 | x | − | 6 | = | 18 |
Transposition :
| 3 | x | = | 18 | + | 6 |
Combine the items on the right of the equation:
| 3 | x | = | 24 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 24 | ÷ | 3 |
| = | 24 | × | 1 3 |
| = | 8 | × | 1 |
We obtained :
| x | = | 8 |
