Work: Find the solution of equation 7200 = x*1.09+1.01 .
Question type: Equation
Solution:Original question:
| 7200 | = | x | × | 109 100 | + | 101 100 |
Transposition :
| - | 109 100 | x | = | 101 100 | − | 7200 |
Combine the items on the right of the equation:
| - | 109 100 | x | = | - | 719899 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
719899 100 | = | 109 100 | 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 :
109 100 | x | = | 719899 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 719899 100 | ÷ | 109 100 |
| = | 719899 100 | × | 100 109 |
| = | 719899 | × | 1 109 |
We obtained :
| x | = | 719899 109 |
Convert the result to decimal form :
| x | = | 6604.577982 |
