Work: Find the solution of equation 151.91+12.51y = 22.85y+26.52 .
Question type: Equation
Solution:Original question:
15191 100 | + | 1251 100 | y | = | 457 20 | y | + | 663 25 |
Transposition :
1251 100 | y | − | 457 20 | y | = | 663 25 | − | 15191 100 |
Combine the items on the left of the equation:
| - | 517 50 | y | = | 663 25 | − | 15191 100 |
Combine the items on the right of the equation:
| - | 517 50 | y | = | - | 12539 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
12539 100 | = | 517 50 | 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 :
517 50 | y | = | 12539 100 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 12539 100 | ÷ | 517 50 |
| = | 12539 100 | × | 50 517 |
| = | 12539 2 | × | 1 517 |
We obtained :
| y | = | 12539 1034 |
Convert the result to decimal form :
| y | = | 12.126692 |
