Work: Find the solution of equation 4x3+0.4x3+0.01x-1.59×0.01 = 0 .
Question type: Equation
Solution:Original question:
| 4 | x | × | 3 | + | 2 5 | x | × | 3 | + | 1 100 | x | − | 159 100 | × | 1 100 | = | 0 |
| Left side of the equation = | 12 | x | + | 6 5 | x | + | 1 100 | x | − | 159 10000 |
| = | 1321 100 | x | − | 159 10000 |
1321 100 | x | − | 159 10000 | = | 0 |
Transposition :
1321 100 | x | = | 0 | + | 159 10000 |
Combine the items on the right of the equation:
1321 100 | x | = | 159 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 159 10000 | ÷ | 1321 100 |
| = | 159 10000 | × | 100 1321 |
| = | 159 100 | × | 1 1321 |
We obtained :
| x | = | 159 132100 |
Convert the result to decimal form :
| x | = | 0.001204 |
