Work: Find the solution of equation (1-x)/1.5 = 0.1782*0.6807*x/(1+0.6807*x) .
Question type: Equation
Solution:Original question:
| ( | 1 | − | x | ) | ÷ | 3 2 | = | 891 5000 | × | 6807 10000 | x | ÷ | ( | 1 | + | 6807 10000 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 6807 10000 | x | ) |
| ( | 1 | − | x | ) | ÷ | 3 2 | × | ( | 1 | + | 6807 10000 | x | ) | = | 891 5000 | × | 6807 10000 | x |
