Work: Find the solution of equation 2.43x-0.46 = -0.0038x4+0.0471x3-0.3005x2+1.2573x .
Question type: Equation
Solution:Original question:
243 100 | x | − | 23 50 | = | - | 19 5000 | x | × | 4 | + | 471 10000 | x | × | 3 | − | 601 2000 | x | × | 2 | + | 12573 10000 | x |
| Right side of the equation = | - | 19 1250 | x | + | 1413 10000 | x | − | 601 1000 | x | + | 12573 10000 | x |
| = | 489 625 | x |
243 100 | x | − | 23 50 | = | 489 625 | x |
Transposition :
243 100 | x | − | 489 625 | x | = | 23 50 |
Combine the items on the left of the equation:
4119 2500 | x | = | 23 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 23 50 | ÷ | 4119 2500 |
| = | 23 50 | × | 2500 4119 |
| = | 23 | × | 50 4119 |
We obtained :
| x | = | 1150 4119 |
Convert the result to decimal form :
| x | = | 0.279194 |
