Work: Find the solution of equation 5.2 = (29000+5.8*x)/(5000+x) .
Question type: Equation
Solution:Original question:
26 5 | = | ( | 29000 | + | 29 5 | x | ) | ÷ | ( | 5000 | + | x | ) |
| Multiply both sides of the equation by: | ( | 5000 | + | x | ) |
26 5 | ( | 5000 | + | x | ) | = | ( | 29000 | + | 29 5 | x | ) |
26 5 | × | 5000 | + | 26 5 | x | = | ( | 29000 | + | 29 5 | x | ) |
26 5 | × | 5000 | + | 26 5 | x | = | 29000 | + | 29 5 | x |
| 26000 | + | 26 5 | x | = | 29000 | + | 29 5 | x |
Transposition :
26 5 | x | − | 29 5 | x | = | 29000 | − | 26000 |
Combine the items on the left of the equation:
| - | 3 5 | x | = | 29000 | − | 26000 |
Combine the items on the right of the equation:
| - | 3 5 | x | = | 3000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 3000 | = | 3 5 | x |
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 :
3 5 | x | = | - | 3000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 3000 | ÷ | 3 5 |
| = | - | 3000 | × | 5 3 |
| = | - | 1000 | × | 5 |
We obtained :
| x | = | - | 5000 |
