Work: Find the solution of equation 0.268x/(0.268x+0.135(1-x)) = 0.7 .
Question type: Equation
Solution:Original question:
67 250 | x | ÷ | ( | 67 250 | x | + | 27 200 | ( | 1 | − | x | ) | ) | = | 7 10 |
| Multiply both sides of the equation by: | ( | 67 250 | x | + | 27 200 | ( | 1 | − | x | ) | ) |
67 250 | x | = | 7 10 | ( | 67 250 | x | + | 27 200 | ( | 1 | − | x | ) | ) |
67 250 | x | = | 7 10 | × | 67 250 | x | + | 7 10 | × | 27 200 | ( | 1 | − | x | ) |
67 250 | x | = | 469 2500 | x | + | 189 2000 | ( | 1 | − | x | ) |
67 250 | x | = | 469 2500 | x | + | 189 2000 | × | 1 | − | 189 2000 | x |
67 250 | x | = | 469 2500 | x | + | 189 2000 | − | 189 2000 | x |
67 250 | x | = | 931 10000 | x | + | 189 2000 |
Transposition :
67 250 | x | − | 931 10000 | x | = | 189 2000 |
Combine the items on the left of the equation:
1749 10000 | x | = | 189 2000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 189 2000 | ÷ | 1749 10000 |
| = | 189 2000 | × | 10000 1749 |
| = | 63 | × | 5 583 |
We obtained :
| x | = | 315 583 |
Convert the result to decimal form :
| x | = | 0.540309 |
