Work: Find the solution of equation 0.15 = 1/(0.04/0.93+0.2/0.13+x/0.023) .
Question type: Equation
Solution:Original question:
3 20 | = | 1 | ÷ | ( | 1 25 | ÷ | 93 100 | + | 1 5 | ÷ | 13 100 | + | x | ÷ | 23 1000 | ) |
| Multiply both sides of the equation by: | ( | 1 25 | ÷ | 93 100 | + | 1 5 | ÷ | 13 100 | + | x | ÷ | 23 1000 | ) |
3 20 | ( | 1 25 | ÷ | 93 100 | + | 1 5 | ÷ | 13 100 | + | x | ÷ | 23 1000 | ) | = | 1 |
3 20 | × | 1 25 | ÷ | 93 100 | + | 3 20 | × | 1 5 | ÷ | 13 100 | + | 3 20 | x | ÷ | 23 1000 | = | 1 |
1 155 | + | 3 13 | + | 150 23 | x | = | 1 |
478 2015 | + | 150 23 | x | = | 1 |
Transposition :
150 23 | x | = | 1 | − | 478 2015 |
Combine the items on the right of the equation:
150 23 | x | = | 1537 2015 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1537 2015 | ÷ | 150 23 |
| = | 1537 2015 | × | 23 150 |
We obtained :
| x | = | 35351 302250 |
Convert the result to decimal form :
| x | = | 0.116959 |
