Work: Find the solution of equation 7/(1-0.577121*x) = 0.2 .
Question type: Equation
Solution:Original question:
| 7 | ÷ | ( | 1 | − | 577121 1000000 | x | ) | = | 1 5 |
| Multiply both sides of the equation by: | ( | 1 | − | 577121 1000000 | x | ) |
| 7 | = | 1 5 | ( | 1 | − | 577121 1000000 | x | ) |
| 7 | = | 1 5 | × | 1 | − | 1 5 | × | 577121 1000000 | x |
| 7 | = | 1 5 | − | 577121 5000000 | x |
Transposition :
577121 5000000 | x | = | 1 5 | − | 7 |
Combine the items on the right of the equation:
577121 5000000 | x | = | - | 34 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 34 5 | ÷ | 577121 5000000 |
| = | - | 34 5 | × | 5000000 577121 |
| = | - | 34 | × | 1000000 577121 |
We obtained :
| x | = | - | 34000000 577121 |
Convert the result to decimal form :
| x | = | - 58.913122 |
