[ 4/5 Equation]
Work: Find the solution of equation 17+9x = 188 .
Question type: Equation
Solution:Original question:
| 17 | + | 9 | x | = | 188 |
Transposition :
| 9 | x | = | 188 | − | 17 |
Combine the items on the right of the equation:
| 9 | x | = | 171 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 171 | ÷ | 9 |
| = | 171 | × | 1 9 |
| = | 19 | × | 1 |
We obtained :
| x | = | 19 |
