Work: Find the solution of equation x/(x+2155.72) = 0.51 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | x | + | 53893 25 | ) | = | 51 100 |
| Multiply both sides of the equation by: | ( | x | + | 53893 25 | ) |
| x | = | 51 100 | ( | x | + | 53893 25 | ) |
| x | = | 51 100 | x | + | 51 100 | × | 53893 25 |
| x | = | 51 100 | x | + | 2748543 2500 |
Transposition :
| x | − | 51 100 | x | = | 2748543 2500 |
Combine the items on the left of the equation:
49 100 | x | = | 2748543 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2748543 2500 | ÷ | 49 100 |
| = | 2748543 2500 | × | 100 49 |
| = | 392649 25 | × | 1 7 |
We obtained :
| x | = | 392649 175 |
Convert the result to decimal form :
| x | = | 2243.708571 |
