Work: Find the solution of equation a/78.11/(a/78.11+(1-a)/92.13) = 0.037 .
Question type: Equation
Solution:Original question:
| a | ÷ | 7811 100 | ÷ | ( | a | ÷ | 7811 100 | + | ( | 1 | − | a | ) | ÷ | 9213 100 | ) | = | 37 1000 |
| Multiply both sides of the equation by: | ( | a | ÷ | 7811 100 | + | ( | 1 | − | a | ) | ÷ | 9213 100 | ) |
| a | ÷ | 7811 100 | = | 37 1000 | ( | a | ÷ | 7811 100 | + | ( | 1 | − | a | ) | ÷ | 9213 100 | ) |
| a | ÷ | 7811 100 | = | 37 1000 | a | ÷ | 7811 100 | + | 37 1000 | ( | 1 | − | a | ) | ÷ | 9213 100 |
| a | × | 100 7811 | = | 37 78110 | a | + | 1 2490 | ( | 1 | − | a | ) |
100 7811 | a | = | 37 78110 | a | + | 1 2490 | × | 1 | − | 1 2490 | a |
100 7811 | a | = | 37 78110 | a | + | 1 2490 | − | 1 2490 | a |
100 7811 | a | = | 701 9724695 | a | + | 1 2490 |
Transposition :
100 7811 | a | − | 701 9724695 | a | = | 1 2490 |
The solution of the equation:
a1≈-5.571327 , keep 6 decimal places
a2≈0.031547 , keep 6 decimal places
There are 2 solution(s).
