Work: Find the solution of equation (x-290.1)/x*100% = -7.4% .
Question type: Equation
Solution:Original question:
| ( | x | − | 2901 10 | ) | ÷ | x | × | 100 100 | = | - | 37 500 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 2901 10 | ) | × | 100 100 | = | - | 37 500 | x |
| x | × | 100 100 | − | 2901 10 | × | 100 100 | = | - | 37 500 | x |
| x | × | 100 100 | − | 2901 10 | = | - | 37 500 | x |
Transposition :
100 100 | x | + | 37 500 | x | = | 2901 10 |
Combine the items on the left of the equation:
537 500 | x | = | 2901 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2901 10 | ÷ | 537 500 |
| = | 2901 10 | × | 500 537 |
| = | 967 | × | 50 179 |
We obtained :
| x | = | 48350 179 |
Convert the result to decimal form :
| x | = | 270.111732 |
