Work: Find the solution of equation 2.5*x/(1+1.5*x) = 3.786*x-1.114 .
Question type: Equation
Solution:Original question:
5 2 | x | ÷ | ( | 1 | + | 3 2 | x | ) | = | 1893 500 | x | − | 557 500 |
| Multiply both sides of the equation by: | ( | 1 | + | 3 2 | x | ) |
5 2 | x | = | 1893 500 | x | ( | 1 | + | 3 2 | x | ) | − | 557 500 | ( | 1 | + | 3 2 | x | ) |
5 2 | x | = | 1893 500 | x | × | 1 | + | 1893 500 | x | × | 3 2 | x | − | 557 500 | ( | 1 | + | 3 2 | x | ) |
5 2 | x | = | 1893 500 | x | + | 5679 1000 | x | x | − | 557 500 | ( | 1 | + | 3 2 | x | ) |
5 2 | x | = | 1893 500 | x | + | 5679 1000 | x | x | − | 557 500 | × | 1 | − | 557 500 | × | 3 2 | x |
5 2 | x | = | 1893 500 | x | + | 5679 1000 | x | x | − | 557 500 | − | 1671 1000 | x |
5 2 | x | = | 423 200 | x | + | 5679 1000 | x | x | − | 557 500 |
The solution of the equation:
x1≈-0.410299 , keep 6 decimal places
x2≈0.478093 , keep 6 decimal places
There are 2 solution(s).
