Work: Find the solution of equation (0.03*2.068+2*x)/(2.068+x)-0.05 = 0 .
Question type: Equation
Solution:Original question:
| ( | 3 100 | × | 517 250 | + | 2 | x | ) | ÷ | ( | 517 250 | + | x | ) | − | 1 20 | = | 0 |
| Multiply both sides of the equation by: | ( | 517 250 | + | x | ) |
| ( | 3 100 | × | 517 250 | + | 2 | x | ) | − | 1 20 | ( | 517 250 | + | x | ) | = | 0 |
3 100 | × | 517 250 | + | 2 | x | − | 1 20 | ( | 517 250 | + | x | ) | = | 0 |
1551 25000 | + | 2 | x | − | 1 20 | ( | 517 250 | + | x | ) | = | 0 |
1551 25000 | + | 2 | x | − | 1 20 | × | 517 250 | − | 1 20 | x | = | 0 |
1551 25000 | + | 2 | x | − | 517 5000 | − | 1 20 | x | = | 0 |
| - | 517 12500 | + | 39 20 | x | = | 0 |
Transposition :
39 20 | x | = | 0 | + | 517 12500 |
Combine the items on the right of the equation:
39 20 | x | = | 517 12500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 517 12500 | ÷ | 39 20 |
| = | 517 12500 | × | 20 39 |
| = | 517 625 | × | 1 39 |
We obtained :
| x | = | 517 24375 |
Convert the result to decimal form :
| x | = | 0.02121 |
