[ 1/1 Equation]
Work: Find the solution of equation 198.475/(n-3) = 492.4938/(n-1) .
Question type: Equation
Solution:Original question:
7939 40 | ÷ | ( | n | − | 3 | ) | = | 2462469 5000 | ÷ | ( | n | − | 1 | ) |
| Multiply both sides of the equation by: | ( | n | − | 3 | ) | , | ( | n | − | 1 | ) |
7939 40 | ( | n | − | 1 | ) | = | 2462469 5000 | ( | n | − | 3 | ) |
7939 40 | n | − | 7939 40 | × | 1 | = | 2462469 5000 | ( | n | − | 3 | ) |
7939 40 | n | − | 7939 40 | × | 1 | = | 2462469 5000 | n | − | 2462469 5000 | × | 3 |
7939 40 | n | − | 7939 40 | = | 2462469 5000 | n | − | 7387407 5000 |
Transposition :
7939 40 | n | − | 2462469 5000 | n | = | - | 7387407 5000 | + | 7939 40 |
Combine the items on the left of the equation:
| - | 735047 2500 | n | = | - | 7387407 5000 | + | 7939 40 |
Combine the items on the right of the equation:
| - | 735047 2500 | n | = | - | 799379 625 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
799379 625 | = | 735047 2500 | n |
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 :
735047 2500 | n | = | 799379 625 |
The coefficient of the unknown number is reduced to 1 :
| n | = | 799379 625 | ÷ | 735047 2500 |
| = | 799379 625 | × | 2500 735047 |
| = | 799379 | × | 4 735047 |
We obtained :
| n | = | 3197516 735047 |
Convert the result to decimal form :
| n | = | 4.350084 |
