Work: Find the solution of equation x/(1.9676-x)*0.3 = 0.72 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 4919 2500 | − | x | ) | × | 3 10 | = | 18 25 |
| Multiply both sides of the equation by: | ( | 4919 2500 | − | x | ) |
| x | × | 3 10 | = | 18 25 | ( | 4919 2500 | − | x | ) |
| x | × | 3 10 | = | 18 25 | × | 4919 2500 | − | 18 25 | x |
| x | × | 3 10 | = | 44271 31250 | − | 18 25 | x |
Transposition :
3 10 | x | + | 18 25 | x | = | 44271 31250 |
Combine the items on the left of the equation:
51 50 | x | = | 44271 31250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 44271 31250 | ÷ | 51 50 |
| = | 44271 31250 | × | 50 51 |
| = | 14757 625 | × | 1 17 |
We obtained :
| x | = | 14757 10625 |
Convert the result to decimal form :
| x | = | 1.388894 |
