Work: Find the solution of equation (10*7*y-467.56)*(1-0.25) = 260 .
Question type: Equation
Solution:Original question:
| ( | 10 | × | 7 | y | − | 11689 25 | ) | ( | 1 | − | 1 4 | ) | = | 260 |
| Left side of the equation = | 10 | × | 7 | y | ( | 1 | − | 1 4 | ) | − | 11689 25 | ( | 1 | − | 1 4 | ) |
| = | 70 | y | ( | 1 | − | 1 4 | ) | − | 11689 25 | ( | 1 | − | 1 4 | ) |
| = | 70 | y | × | 1 | − | 70 | y | × | 1 4 | − | 11689 25 | ( | 1 | − | 1 4 | ) |
| = | 70 | y | − | 35 2 | y | − | 11689 25 | ( | 1 | − | 1 4 | ) |
| = | 105 2 | y | − | 11689 25 | ( | 1 | − | 1 4 | ) |
| = | 105 2 | y | − | 11689 25 | × | 1 | + | 11689 25 | × | 1 4 |
| = | 105 2 | y | − | 11689 25 | + | 11689 100 |
| = | 105 2 | y | − | 35067 100 |
105 2 | y | − | 35067 100 | = | 260 |
Transposition :
105 2 | y | = | 260 | + | 35067 100 |
Combine the items on the right of the equation:
105 2 | y | = | 61067 100 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 61067 100 | ÷ | 105 2 |
| = | 61067 100 | × | 2 105 |
| = | 61067 50 | × | 1 105 |
We obtained :
| y | = | 61067 5250 |
Convert the result to decimal form :
| y | = | 11.63181 |
