[ 1/1 Equation]
Work: Find the solution of equation (x-29.17)/x = 77% .
Question type: Equation
Solution:Original question:
| ( | x | − | 2917 100 | ) | ÷ | x | = | 77 100 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 2917 100 | ) | = | 77 100 | x |
| x | − | 2917 100 | = | 77 100 | x |
Transposition :
| x | − | 77 100 | x | = | 2917 100 |
Combine the items on the left of the equation:
23 100 | x | = | 2917 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2917 100 | ÷ | 23 100 |
| = | 2917 100 | × | 100 23 |
| = | 2917 | × | 1 23 |
We obtained :
| x | = | 2917 23 |
Convert the result to decimal form :
| x | = | 126.826087 |
