Work: Find the solution of equation 14.5x+320000 = 20x .
Question type: Equation
Solution:Original question:
29 2 | x | + | 320000 | = | 20 | x |
Transposition :
29 2 | x | − | 20 | x | = | - | 320000 |
Combine the items on the left of the equation:
| - | 11 2 | x | = | - | 320000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 320000 | = | 11 2 | 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 :
11 2 | x | = | 320000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 320000 | ÷ | 11 2 |
| = | 320000 | × | 2 11 |
We obtained :
| x | = | 640000 11 |
Convert the result to decimal form :
| x | = | 58181.818182 |
