Work: Find the solution of equation -45.49 = 1.061×15.3X-6.8X .
Question type: Equation
Solution:Original question:
| - | 4549 100 | = | 1061 1000 | × | 153 10 | X | − | 34 5 | X |
| Right side of the equation = | 162333 10000 | X | − | 34 5 | X |
| = | 94333 10000 | X |
| - | 4549 100 | = | 94333 10000 | X |
Transposition :
| - | 94333 10000 | X | = | 4549 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 4549 100 | = | 94333 10000 | 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 :
94333 10000 | X | = | - | 4549 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 4549 100 | ÷ | 94333 10000 |
| = | - | 4549 100 | × | 10000 94333 |
| = | - | 4549 | × | 100 94333 |
We obtained :
| X | = | - | 454900 94333 |
Convert the result to decimal form :
| X | = | - 4.822279 |
