Work: Find the solution of equation -14.44x+639.72 = -0.65x+287.4 .
Question type: Equation
Solution:Original question:
| - | 361 25 | x | + | 15993 25 | = | - | 13 20 | x | + | 1437 5 |
Transposition :
| - | 361 25 | x | + | 13 20 | x | = | 1437 5 | − | 15993 25 |
Combine the items on the left of the equation:
| - | 1379 100 | x | = | 1437 5 | − | 15993 25 |
Combine the items on the right of the equation:
| - | 1379 100 | x | = | - | 8808 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
8808 25 | = | 1379 100 | 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 :
1379 100 | x | = | 8808 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 8808 25 | ÷ | 1379 100 |
| = | 8808 25 | × | 100 1379 |
| = | 8808 | × | 4 1379 |
We obtained :
| x | = | 35232 1379 |
Convert the result to decimal form :
| x | = | 25.548949 |
