Work: Find the solution of equation 164.62×7.99-12.25x = 164.62×7.97 .
Question type: Equation
Solution:Original question:
8231 50 | × | 799 100 | − | 49 4 | x | = | 8231 50 | × | 797 100 |
| Left side of the equation = | 6576569 5000 | − | 49 4 | x |
6576569 5000 | − | 49 4 | x | = | 8231 50 | × | 797 100 |
| Right side of the equation = | 6560107 5000 |
6576569 5000 | − | 49 4 | x | = | 6560107 5000 |
Transposition :
| - | 49 4 | x | = | 6560107 5000 | − | 6576569 5000 |
Combine the items on the right of the equation:
| - | 49 4 | x | = | - | 8231 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
8231 2500 | = | 49 4 | 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 :
49 4 | x | = | 8231 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 8231 2500 | ÷ | 49 4 |
| = | 8231 2500 | × | 4 49 |
| = | 8231 625 | × | 1 49 |
We obtained :
| x | = | 8231 30625 |
Convert the result to decimal form :
| x | = | 0.268767 |
