Work: Find the solution of equation (y-0.936)/0.936 = 1.08(y-1) .
Question type: Equation
Solution:Original question:
| ( | y | − | 117 125 | ) | ÷ | 117 125 | = | 27 25 | ( | y | − | 1 | ) |
| Left side of the equation = | y | × | 125 117 | − | 117 125 | × | 125 117 |
| = | y | × | 125 117 | − | 1 |
125 117 | y | − | 1 | = | 27 25 | ( | y | − | 1 | ) |
| Right side of the equation = | 27 25 | y | − | 27 25 | × | 1 |
| = | 27 25 | y | − | 27 25 |
125 117 | y | − | 1 | = | 27 25 | y | − | 27 25 |
Transposition :
125 117 | y | − | 27 25 | y | = | - | 27 25 | + | 1 |
Combine the items on the left of the equation:
| - | 34 2925 | y | = | - | 27 25 | + | 1 |
Combine the items on the right of the equation:
| - | 34 2925 | y | = | - | 2 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2 25 | = | 34 2925 | 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 :
34 2925 | y | = | 2 25 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 2 25 | ÷ | 34 2925 |
| = | 2 25 | × | 2925 34 |
| = | 1 | × | 117 17 |
We obtained :
| y | = | 117 17 |
Convert the result to decimal form :
| y | = | 6.882353 |
