Work: Find the solution of equation 7y-467.56-(7y*13%-112-14)*10%-(7y-467.56)*25% = 0 .
Question type: Equation
Solution:Original question:
| 7 | y | − | 11689 25 | − | ( | 7 | y | × | 13 100 | − | 112 | − | 14 | ) | × | 10 100 | − | ( | 7 | y | − | 11689 25 | ) | × | 25 100 | = | 0 |
| Left side of the equation = | 7 | y | − | 11689 25 | − | 7 | y | × | 13 100 | × | 10 100 | + | 112 | × | 10 100 | + | 14 | × | 10 100 | − | ( | 7 | y | − | 11689 25 | ) |
| = | 7 | y | − | 11689 25 | − | 91 1000 | y | + | 56 5 | + | 7 5 | − | ( | 7 | y | − | 11689 25 | ) | × | 25 100 |
| = | 6909 1000 | y | − | 11374 25 | − | ( | 7 | y | − | 11689 25 | ) | × | 25 100 |
| = | 6909 1000 | y | − | 11374 25 | − | 7 | y | × | 25 100 | + | 11689 25 | × | 25 100 |
| = | 6909 1000 | y | − | 11374 25 | − | 7 4 | y | + | 11689 100 |
| = | 5159 1000 | y | − | 33807 100 |
5159 1000 | y | − | 33807 100 | = | 0 |
Transposition :
5159 1000 | y | = | 0 | + | 33807 100 |
Combine the items on the right of the equation:
5159 1000 | y | = | 33807 100 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 33807 100 | ÷ | 5159 1000 |
| = | 33807 100 | × | 1000 5159 |
| = | 33807 | × | 10 5159 |
We obtained :
| y | = | 338070 5159 |
Convert the result to decimal form :
| y | = | 65.530142 |
