[ 1/1 Equation]
Work: Find the solution of equation -99X-0.738X = 0.257-45 .
Question type: Equation
Solution:Original question:
| - | 99 | X | − | 369 500 | X | = | 257 1000 | − | 45 |
| Left side of the equation = | - | 49869 500 | X |
| - | 49869 500 | X | = | 257 1000 | − | 45 |
| Right side of the equation = | - | 44743 1000 |
| - | 49869 500 | X | = | - | 44743 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
44743 1000 | = | 49869 500 | 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 :
49869 500 | X | = | 44743 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 44743 1000 | ÷ | 49869 500 |
| = | 44743 1000 | × | 500 49869 |
| = | 44743 2 | × | 1 49869 |
We obtained :
| X | = | 44743 99738 |
Convert the result to decimal form :
| X | = | 0.448605 |
