Work: Find the solution of equation （3.5+x）×7.97 = 12.13x .
Question type: Equation
Solution:Original question:
| ( | 7 2 | + | x | ) | × | 797 100 | = | 1213 100 | x |
| Left side of the equation = | 7 2 | × | 797 100 | + | x | × | 797 100 |
| = | 5579 200 | + | x | × | 797 100 |
5579 200 | + | 797 100 | x | = | 1213 100 | x |
Transposition :
797 100 | x | − | 1213 100 | x | = | - | 5579 200 |
Combine the items on the left of the equation:
| - | 104 25 | x | = | - | 5579 200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5579 200 | = | 104 25 | 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 :
104 25 | x | = | 5579 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5579 200 | ÷ | 104 25 |
| = | 5579 200 | × | 25 104 |
| = | 5579 8 | × | 1 104 |
We obtained :
| x | = | 5579 832 |
Convert the result to decimal form :
| x | = | 6.705529 |
