Work: Find the solution of equation 4.22×5.1÷2640×x＋1.65 = 1.6806 .
Question type: Equation
Solution:Original question:
211 50 | × | 51 10 | ÷ | 2640 | × | x | + | 33 20 | = | 8403 5000 |
| Left side of the equation = | 3587 440000 | x | + | 33 20 |
3587 440000 | x | + | 33 20 | = | 8403 5000 |
Transposition :
3587 440000 | x | = | 8403 5000 | − | 33 20 |
Combine the items on the right of the equation:
3587 440000 | x | = | 153 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 153 5000 | ÷ | 3587 440000 |
| = | 153 5000 | × | 440000 3587 |
| = | 153 | × | 88 3587 |
We obtained :
| x | = | 13464 3587 |
By reducing fraction, we can get:
| x | = | 792 211 |
Convert the result to decimal form :
| x | = | 3.753555 |
