Work: Find the solution of equation (64.49-y)/y = -0.0295-(y-66.45)/66.45 .
Question type: Equation
Solution:Original question:
| ( | 6449 100 | − | y | ) | ÷ | y | = | - | 59 2000 | − | ( | y | − | 1329 20 | ) | ÷ | 1329 20 |
| Multiply both sides of the equation by: | y |
| ( | 6449 100 | − | y | ) | = | - | 59 2000 | y | − | ( | y | − | 1329 20 | ) | ÷ | 1329 20 | × | y |
6449 100 | − | y | = | - | 59 2000 | y | − | ( | y | − | 1329 20 | ) | ÷ | 1329 20 | × | y |
6449 100 | − | y | = | - | 59 2000 | y | − | y | ÷ | 1329 20 | × | y | + | 1329 20 | ÷ | 1329 20 | × | y |
6449 100 | − | y | = | - | 59 2000 | y | − | y | × | 20 1329 | y | + | 1 | y |
6449 100 | − | y | = | 1941 2000 | y | − | y | × | 20 1329 | y |
The solution of the equation:
y1≈64.499092 , keep 6 decimal places
y2≈66.440633 , keep 6 decimal places
There are 2 solution(s).
