[ 1/1 Equation]
Work: Find the solution of equation (5-x)/0.5 = 0.2195*0.5564*x/(1+0.5564*x) .
Question type: Equation
Solution:Original question:
| ( | 5 | − | x | ) | ÷ | 1 2 | = | 439 2000 | × | 1391 2500 | x | ÷ | ( | 1 | + | 1391 2500 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 1391 2500 | x | ) |
| ( | 5 | − | x | ) | ÷ | 1 2 | × | ( | 1 | + | 1391 2500 | x | ) | = | 439 2000 | × | 1391 2500 | x |
| 5 | ÷ | 1 2 | × | ( | 1 | + | 1391 2500 | x | ) | − | x | ÷ | 1 2 | × | ( | 1 | + | 1391 2500 | x | ) | = | 439 2000 | × | 1391 2500 | x |
| 10 | ( | 1 | + | 1391 2500 | x | ) | − | x | × | 2 | ( | 1 | + | 1391 2500 | x | ) | = | 610649 5000000 | x |
| 10 | × | 1 | + | 10 | × | 1391 2500 | x | − | x | × | 2 | ( | 1 | + | 1391 2500 | x | ) | = | 610649 5000000 | x |
| 10 | + | 1391 250 | x | − | x | × | 2 | ( | 1 | + | 1391 2500 | x | ) | = | 610649 5000000 | x |
| 10 | + | 1391 250 | x | − | x | × | 2 | × | 1 | − | x | × | 2 | × | 1391 2500 | x | = | 610649 5000000 | x |
| 10 | + | 1391 250 | x | − | x | × | 2 | − | x | × | 1391 1250 | x | = | 610649 5000000 | x |
| 10 | + | 891 250 | x | − | x | × | 1391 1250 | x | = | 610649 5000000 | x |
