Work: Find the solution of equation 14 = 1.205*(1+220/x) .
Question type: Equation
Solution:Original question:
| 14 | = | 241 200 | ( | 1 | + | 220 | ÷ | x | ) |
| 14 | = | 241 200 | × | 1 | + | 241 200 | × | 220 | ÷ | x |
| 14 | = | 241 200 | + | 2651 10 | ÷ | x |
| Multiply both sides of the equation by: | x |
| 14 | x | = | 241 200 | x | + | 2651 10 |
Transposition :
| 14 | x | − | 241 200 | x | = | 2651 10 |
Combine the items on the left of the equation:
2559 200 | x | = | 2651 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2651 10 | ÷ | 2559 200 |
| = | 2651 10 | × | 200 2559 |
| = | 2651 | × | 20 2559 |
We obtained :
| x | = | 53020 2559 |
Convert the result to decimal form :
| x | = | 20.719031 |
