Work: Find the solution of equation x*7-196--183.36-1040*0.8-5 = 102.19 .
Question type: Equation
Solution:Original question:
| x | × | 7 | − | 196 | − | 4584 25 | − | 1040 | × | 4 5 | − | 5 | = | 10219 100 |
| Left side of the equation = | x | × | 7 | − | 196 | − | 4584 25 | − | 832 | − | 5 |
| = | 7 | x | − | 30409 25 |
| 7 | x | − | 30409 25 | = | 10219 100 |
Transposition :
| 7 | x | = | 10219 100 | + | 30409 25 |
Combine the items on the right of the equation:
| 7 | x | = | 26371 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 26371 20 | ÷ | 7 |
| = | 26371 20 | × | 1 7 |
We obtained :
| x | = | 26371 140 |
Convert the result to decimal form :
| x | = | 188.364286 |
