Work: Find the solution of equation 0 = 314.8530+1.7696*0-0.4173y-0.0870*0-0.0076y2 .
Question type: Equation
Solution:Original question:
| 0 | = | 314853 1000 | + | 1106 625 | × | 0 | − | 4173 10000 | y | − | 87 1000 | × | 0 | − | 19 2500 | y | × | 2 |
| Right side of the equation = | 314853 1000 | + | 0 | − | 4173 10000 | y | − | 0 | − | 19 1250 | y |
| = | 314853 1000 | − | 173 400 | y |
| 0 | = | 314853 1000 | − | 173 400 | y |
Transposition :
173 400 | y | = | 314853 1000 | − | 0 |
Combine the items on the right of the equation:
173 400 | y | = | 314853 1000 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 314853 1000 | ÷ | 173 400 |
| = | 314853 1000 | × | 400 173 |
| = | 314853 5 | × | 2 173 |
We obtained :
| y | = | 629706 865 |
Convert the result to decimal form :
| y | = | 727.983815 |
