[ 1/1 Equation]
Work: Find the solution of equation 3X+16 = 91 .
Question type: Equation
Solution:Original question:
| 3 | X | + | 16 | = | 91 |
Transposition :
| 3 | X | = | 91 | − | 16 |
Combine the items on the right of the equation:
| 3 | X | = | 75 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 75 | ÷ | 3 |
| = | 75 | × | 1 3 |
| = | 25 | × | 1 |
We obtained :
| X | = | 25 |
