Work: Find the solution of equation （x-13.3）/x = 0.987 .
Question type: Equation
Solution:Original question:
| ( | x | − | 133 10 | ) | ÷ | x | = | 987 1000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 133 10 | ) | = | 987 1000 | x |
| x | − | 133 10 | = | 987 1000 | x |
Transposition :
| x | − | 987 1000 | x | = | 133 10 |
Combine the items on the left of the equation:
13 1000 | x | = | 133 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 133 10 | ÷ | 13 1000 |
| = | 133 10 | × | 1000 13 |
| = | 133 | × | 100 13 |
We obtained :
| x | = | 13300 13 |
Convert the result to decimal form :
| x | = | 1023.076923 |
