Work: Find the solution of equation 83.44 = 96.89X+79.29*0.7 .
Question type: Equation
Solution:Original question:
2086 25 | = | 9689 100 | X | + | 7929 100 | × | 7 10 |
| Right side of the equation = | 9689 100 | X | + | 55503 1000 |
2086 25 | = | 9689 100 | X | + | 55503 1000 |
Transposition :
| - | 9689 100 | X | = | 55503 1000 | − | 2086 25 |
Combine the items on the right of the equation:
| - | 9689 100 | X | = | - | 27937 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
27937 1000 | = | 9689 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 :
9689 100 | X | = | 27937 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 27937 1000 | ÷ | 9689 100 |
| = | 27937 1000 | × | 100 9689 |
| = | 27937 10 | × | 1 9689 |
We obtained :
| X | = | 27937 96890 |
Convert the result to decimal form :
| X | = | 0.288337 |
