Work: Find the solution of equation 213162.619+(y-y*0.825)/1.05*0.05 = y .
Question type: Equation
Solution:Original question:
213162619 1000 | + | ( | y | − | y | × | 33 40 | ) | ÷ | 21 20 | × | 1 20 | = | y |
| Left side of the equation = | 213162619 1000 | + | ( | y | − | y | × | 33 40 | ) | × | 1 21 |
213162619 1000 | + | ( | y | − | y | × | 33 40 | ) | × | 1 21 | = | y |
| Left side of the equation = | 213162619 1000 | + | y | × | 1 21 | − | y | × | 33 40 | × | 1 21 |
| = | 213162619 1000 | + | y | × | 1 21 | − | y | × | 11 280 |
| = | 213162619 1000 | + | 1 120 | y |
213162619 1000 | + | 1 120 | y | = | y |
Transposition :
1 120 | y | − | y | = | - | 213162619 1000 |
Combine the items on the left of the equation:
| - | 119 120 | y | = | - | 213162619 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
213162619 1000 | = | 119 120 | 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 :
119 120 | y | = | 213162619 1000 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 213162619 1000 | ÷ | 119 120 |
| = | 213162619 1000 | × | 120 119 |
| = | 213162619 25 | × | 3 119 |
We obtained :
| y | = | 639487857 2975 |
Convert the result to decimal form :
| y | = | 214953.901513 |
