[ 1/1 Equation]
Work: Find the solution of equation 6(x-3) = 84 .
Question type: Equation
Solution:Original question:
| 6 | ( | x | − | 3 | ) | = | 84 |
| Left side of the equation = | 6 | x | − | 6 | × | 3 |
| = | 6 | x | − | 18 |
| 6 | x | − | 18 | = | 84 |
Transposition :
| 6 | x | = | 84 | + | 18 |
Combine the items on the right of the equation:
| 6 | x | = | 102 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 102 | ÷ | 6 |
| = | 102 | × | 1 6 |
| = | 17 | × | 1 |
We obtained :
| x | = | 17 |
