Work: Find the solution of equation 14.7% = （1.44-x)/x*100% .
Question type: Equation
Solution:Original question:
147 1000 | = | ( | 36 25 | − | x | ) | ÷ | x | × | 100 100 |
| Multiply both sides of the equation by: | x |
147 1000 | x | = | ( | 36 25 | − | x | ) | × | 100 100 |
147 1000 | x | = | 36 25 | × | 100 100 | − | x | × | 100 100 |
147 1000 | x | = | 36 25 | − | x | × | 100 100 |
Transposition :
147 1000 | x | + | 100 100 | x | = | 36 25 |
Combine the items on the left of the equation:
1147 1000 | x | = | 36 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 36 25 | ÷ | 1147 1000 |
| = | 36 25 | × | 1000 1147 |
| = | 36 | × | 40 1147 |
We obtained :
| x | = | 1440 1147 |
Convert the result to decimal form :
| x | = | 1.255449 |
