Work: Find the solution of equation (2.5*x)/(1.5*x+1) = 0.955 .
Question type: Equation
Solution:Original question:
| ( | 5 2 | x | ) | ÷ | ( | 3 2 | x | + | 1 | ) | = | 191 200 |
| Multiply both sides of the equation by: | ( | 3 2 | x | + | 1 | ) |
| ( | 5 2 | x | ) | = | 191 200 | ( | 3 2 | x | + | 1 | ) |
5 2 | x | = | 191 200 | ( | 3 2 | x | + | 1 | ) |
5 2 | x | = | 191 200 | × | 3 2 | x | + | 191 200 | × | 1 |
5 2 | x | = | 573 400 | x | + | 191 200 |
Transposition :
5 2 | x | − | 573 400 | x | = | 191 200 |
Combine the items on the left of the equation:
427 400 | x | = | 191 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 191 200 | ÷ | 427 400 |
| = | 191 200 | × | 400 427 |
| = | 191 | × | 2 427 |
We obtained :
| x | = | 382 427 |
Convert the result to decimal form :
| x | = | 0.894614 |
