[ 1/1 Equation]
Work: Find the solution of equation 67（164.13-y）+57y = 10.28 .
Question type: Equation
Solution:Original question:
| 67 | ( | 16413 100 | − | y | ) | + | 57 | y | = | 257 25 |
| Left side of the equation = | 67 | × | 16413 100 | − | 67 | y | + | 57 | y |
| = | 1099671 100 | − | 67 | y | + | 57 | y |
| = | 1099671 100 | − | 10 | y |
1099671 100 | − | 10 | y | = | 257 25 |
Transposition :
| - | 10 | y | = | 257 25 | − | 1099671 100 |
Combine the items on the right of the equation:
| - | 10 | y | = | - | 1098643 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1098643 100 | = | 10 | y |
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 :
| 10 | y | = | 1098643 100 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 1098643 100 | ÷ | 10 |
| = | 1098643 100 | × | 1 10 |
We obtained :
| y | = | 1098643 1000 |
Convert the result to decimal form :
| y | = | 1098.643 |
