Work: Find the solution of equation 0.4532 = 0.137X-3+0.119X-2+0.269X-1-0.019 .
Question type: Equation
Solution:Original question:
1133 2500 | = | 137 1000 | X | − | 3 | + | 119 1000 | X | − | 2 | + | 269 1000 | X | − | 1 | − | 19 1000 |
| Right side of the equation = | 21 40 | X | − | 6019 1000 |
1133 2500 | = | 21 40 | X | − | 6019 1000 |
Transposition :
| - | 21 40 | X | = | - | 6019 1000 | − | 1133 2500 |
Combine the items on the right of the equation:
| - | 21 40 | X | = | - | 32361 5000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
32361 5000 | = | 21 40 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
21 40 | X | = | 32361 5000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 32361 5000 | ÷ | 21 40 |
| = | 32361 5000 | × | 40 21 |
| = | 1541 125 | × | 1 |
We obtained :
| X | = | 1541 125 |
Convert the result to decimal form :
| X | = | 12.328 |
