Work: Find the solution of equation 1/2*(x/3882.8+3882.8/3011.79）-1 = 0.15 .
Question type: Equation
Solution:Original question:
| 1 | ÷ | 2 | × | ( | x | ÷ | 19414 5 | + | 19414 5 | ÷ | 301179 100 | ) | − | 1 | = | 3 20 |
| Left side of the equation = | 1 2 | ( | x | ÷ | 19414 5 | + | 19414 5 | ÷ | 301179 100 | ) | − | 1 |
1 2 | ( | x | ÷ | 19414 5 | + | 19414 5 | ÷ | 301179 100 | ) | − | 1 | = | 3 20 |
| Left side of the equation = | 1 2 | x | ÷ | 19414 5 | + | 1 2 | × | 19414 5 | ÷ | 301179 100 | − | 1 |
| = | 5 38828 | x | + | 194140 301179 | − | 1 |
| = | 5 38828 | x | − | 107039 301179 |
5 38828 | x | − | 107039 301179 | = | 3 20 |
Transposition :
5 38828 | x | = | 3 20 | + | 107039 301179 |
Combine the items on the right of the equation:
5 38828 | x | = | 3044317 6023580 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3044317 6023580 | ÷ | 5 38828 |
| = | 3044317 6023580 | × | 38828 5 |
| = | 3044317 1505895 | × | 9707 5 |
We obtained :
| x | = | 29551185119 7529475 |
