[ 1/1 Equation]
Work: Find the solution of equation (square5-4)/2 = 0 .
Question type: Equation
Solution:Original question:
| ( | s | × | 5 | − | 4 | ) | ÷ | 2 | = | 0 |
| Left side of the equation = | s | × | 5 | × | 1 2 | − | 4 | × | 1 2 |
| = | s | × | 5 2 | − | 2 |
5 2 | s | − | 2 | = | 0 |
Transposition :
5 2 | s | = | 0 | + | 2 |
Combine the items on the right of the equation:
5 2 | s | = | 2 |
The coefficient of the unknown number is reduced to 1 :
| s | = | 2 | ÷ | 5 2 |
| = | 2 | × | 2 5 |
We obtained :
| s | = | 4 5 |
Convert the result to decimal form :
| s | = | 0.8 |
