Work: Find the solution of equation (3.5-x)/1.5 = 0.1724*0.6642*x/(1+0.6642*x) .
Question type: Equation
Solution:Original question:
| ( | 7 2 | − | x | ) | ÷ | 3 2 | = | 431 2500 | × | 3321 5000 | x | ÷ | ( | 1 | + | 3321 5000 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 3321 5000 | x | ) |
| ( | 7 2 | − | x | ) | ÷ | 3 2 | × | ( | 1 | + | 3321 5000 | x | ) | = | 431 2500 | × | 3321 5000 | x |
