Work: Find the solution of equation {0.25x/(0.25x+100)} = 1.7x/(x+100) .
Question type: Equation
Solution:Original question:
| ( | 1 4 | x | ÷ | ( | 1 4 | x | + | 100 | ) | ) | = | 17 10 | x | ÷ | ( | x | + | 100 | ) |
| Multiply both sides of the equation by: | ( | x | + | 100 | ) |
| ( | 1 4 | x | ÷ | ( | 1 4 | x | + | 100 | ) | ) | ( | x | + | 100 | ) | = | 17 10 | x |
1 4 | x | ÷ | ( | 1 4 | x | + | 100 | ) | × | ( | x | + | 100 | ) | = | 17 10 | x |
| Multiply both sides of the equation by: | ( | 1 4 | x | + | 100 | ) |
1 4 | x | ( | x | + | 100 | ) | = | 17 10 | x | ( | 1 4 | x | + | 100 | ) |
1 4 | x | x | + | 1 4 | x | × | 100 | = | 17 10 | x | ( | 1 4 | x | + | 100 | ) |
1 4 | x | x | + | 1 4 | x | × | 100 | = | 17 10 | x | × | 1 4 | x | + | 17 10 | x | × | 100 |
1 4 | x | x | + | 25 | x | = | 17 40 | x | x | + | 170 | x |
the solutions is:
x1=0
There are 1 solution(s).
