[ 1/2 Equation]
Work: Find the solution of equation (x/3.97)/(x/3.97+3.3/1.27) = 0 .
Question type: Equation
Solution:Original question:
| ( | x | ÷ | 397 100 | ) | ÷ | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) |
| ( | x | ÷ | 397 100 | ) | = | 0 |
| x | ÷ | 397 100 | = | 0 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 0 | ÷ | 100 397 |
| = | 0 | × | 397 100 |
We obtained :
| x | = | 0 |
