[ 1/1 Equation]
Work: Find the solution of equation (885*0.579+x)/(885+x) = 0.6 .
Question type: Equation
Solution:Original question:
| ( | 885 | × | 579 1000 | + | x | ) | ÷ | ( | 885 | + | x | ) | = | 3 5 |
| Multiply both sides of the equation by: | ( | 885 | + | x | ) |
| ( | 885 | × | 579 1000 | + | x | ) | = | 3 5 | ( | 885 | + | x | ) |
| 885 | × | 579 1000 | + | x | = | 3 5 | ( | 885 | + | x | ) |
| 885 | × | 579 1000 | + | x | = | 3 5 | × | 885 | + | 3 5 | x |
102483 200 | + | x | = | 531 | + | 3 5 | x |
Transposition :
| x | − | 3 5 | x | = | 531 | − | 102483 200 |
Combine the items on the left of the equation:
2 5 | x | = | 531 | − | 102483 200 |
Combine the items on the right of the equation:
2 5 | x | = | 3717 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3717 200 | ÷ | 2 5 |
| = | 3717 200 | × | 5 2 |
| = | 3717 40 | × | 1 2 |
We obtained :
| x | = | 3717 80 |
Convert the result to decimal form :
| x | = | 46.4625 |
