Work: Find the solution of equation 0.0138x3-7.6223x2+1269.6x+204578 = 269676 .
Question type: Equation
Solution:Original question:
69 5000 | x | × | 3 | − | 76223 10000 | x | × | 2 | + | 6348 5 | x | + | 204578 | = | 269676 |
| Left side of the equation = | 207 5000 | x | − | 76223 5000 | x | + | 6348 5 | x | + | 204578 |
| = | 783998 625 | x | + | 204578 |
783998 625 | x | + | 204578 | = | 269676 |
Transposition :
783998 625 | x | = | 269676 | − | 204578 |
Combine the items on the right of the equation:
783998 625 | x | = | 65098 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 65098 | ÷ | 783998 625 |
| = | 65098 | × | 625 783998 |
| = | 32549 | × | 625 391999 |
We obtained :
| x | = | 20343125 391999 |
Convert the result to decimal form :
| x | = | 51.895859 |
