[ 1/1 Equation]
Work: Find the solution of equation 688.66-10.5×33.22-5.5x = 0 .
Question type: Equation
Solution:Original question:
34433 50 | − | 21 2 | × | 1661 50 | − | 11 2 | x | = | 0 |
| Left side of the equation = | 34433 50 | − | 34881 100 | − | 11 2 | x |
| = | 6797 20 | − | 11 2 | x |
6797 20 | − | 11 2 | x | = | 0 |
Transposition :
| - | 11 2 | x | = | 0 | − | 6797 20 |
Combine the items on the right of the equation:
| - | 11 2 | x | = | - | 6797 20 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
6797 20 | = | 11 2 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
11 2 | x | = | 6797 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6797 20 | ÷ | 11 2 |
| = | 6797 20 | × | 2 11 |
| = | 6797 10 | × | 1 11 |
We obtained :
| x | = | 6797 110 |
Convert the result to decimal form :
| x | = | 61.790909 |
