☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation 2X+8 = 5 .
Question type: Equation
Solution:Original question:
| 2 | X | + | 8 | = | 5 |
Transposition :
| 2 | X | = | 5 | − | 8 |
Combine the items on the right of the equation:
| 2 | X | = | - | 3 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 3 | ÷ | 2 |
| = | - | 3 | × | 1 2 |
We obtained :
| X | = | - | 3 2 |
Convert the result to decimal form :
| X | = | - 1.5 |
