Work: Find the solution of equation 5.73y-46.2+10y+81.1 = 6.93y+20.8+10y .
Question type: Equation
Solution:Original question:
573 100 | y | − | 231 5 | + | 10 | y | + | 811 10 | = | 693 100 | y | + | 104 5 | + | 10 | y |
| Left side of the equation = | 1573 100 | y | + | 349 10 |
1573 100 | y | + | 349 10 | = | 693 100 | y | + | 104 5 | + | 10 | y |
| Right side of the equation = | 1693 100 | y | + | 104 5 |
1573 100 | y | + | 349 10 | = | 1693 100 | y | + | 104 5 |
Transposition :
1573 100 | y | − | 1693 100 | y | = | 104 5 | − | 349 10 |
Combine the items on the left of the equation:
| - | 6 5 | y | = | 104 5 | − | 349 10 |
Combine the items on the right of the equation:
| - | 6 5 | y | = | - | 141 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
141 10 | = | 6 5 | 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 :
6 5 | y | = | 141 10 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 141 10 | ÷ | 6 5 |
| = | 141 10 | × | 5 6 |
| = | 47 2 | × | 1 2 |
We obtained :
| y | = | 47 4 |
Convert the result to decimal form :
| y | = | 11.75 |
