Work: Find the solution of equation (701860+14807X)/(40+X) = 14914.53 .
Question type: Equation
Solution:Original question:
| ( | 701860 | + | 14807 | X | ) | ÷ | ( | 40 | + | X | ) | = | 1491453 100 |
| Multiply both sides of the equation by: | ( | 40 | + | X | ) |
| ( | 701860 | + | 14807 | X | ) | = | 1491453 100 | ( | 40 | + | X | ) |
| 701860 | + | 14807 | X | = | 1491453 100 | ( | 40 | + | X | ) |
| 701860 | + | 14807 | X | = | 1491453 100 | × | 40 | + | 1491453 100 | X |
| 701860 | + | 14807 | X | = | 2982906 5 | + | 1491453 100 | X |
Transposition :
| 14807 | X | − | 1491453 100 | X | = | 2982906 5 | − | 701860 |
Combine the items on the left of the equation:
| - | 10753 100 | X | = | 2982906 5 | − | 701860 |
Combine the items on the right of the equation:
| - | 10753 100 | X | = | - | 526394 5 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
526394 5 | = | 10753 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 :
10753 100 | X | = | 526394 5 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 526394 5 | ÷ | 10753 100 |
| = | 526394 5 | × | 100 10753 |
| = | 526394 | × | 20 10753 |
We obtained :
| X | = | 10527880 10753 |
Convert the result to decimal form :
| X | = | 979.064447 |
