[ 1/1 Equation]
Work: Find the solution of equation 81.9207/X = 1.05 .
Question type: Equation
Solution:Original question:
819207 10000 | ÷ | X | = | 21 20 |
| Multiply both sides of the equation by: | X |
819207 10000 | = | 21 20 | X |
Transposition :
| - | 21 20 | X | = | - | 819207 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
819207 10000 | = | 21 20 | 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 20 | X | = | 819207 10000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 819207 10000 | ÷ | 21 20 |
| = | 819207 10000 | × | 20 21 |
| = | 273069 500 | × | 1 7 |
We obtained :
| X | = | 273069 3500 |
Convert the result to decimal form :
| X | = | 78.019714 |
