Work: Find the solution of equation (1694663.6+x)/(101089.92+x) = 0.3 .
Question type: Equation
Solution:Original question:
| ( | 8473318 5 | + | x | ) | ÷ | ( | 2527248 25 | + | x | ) | = | 3 10 |
| Multiply both sides of the equation by: | ( | 2527248 25 | + | x | ) |
| ( | 8473318 5 | + | x | ) | = | 3 10 | ( | 2527248 25 | + | x | ) |
8473318 5 | + | x | = | 3 10 | ( | 2527248 25 | + | x | ) |
8473318 5 | + | x | = | 3 10 | × | 2527248 25 | + | 3 10 | x |
8473318 5 | + | x | = | 3790872 125 | + | 3 10 | x |
Transposition :
| x | − | 3 10 | x | = | 3790872 125 | − | 8473318 5 |
Combine the items on the left of the equation:
7 10 | x | = | 3790872 125 | − | 8473318 5 |
Combine the items on the right of the equation:
7 10 | x | = | - | 208042078 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 208042078 125 | ÷ | 7 10 |
| = | - | 208042078 125 | × | 10 7 |
| = | - | 208042078 25 | × | 2 7 |
We obtained :
| x | = | - | 416084156 175 |
Convert the result to decimal form :
| x | = | - 2377623.748571 |
