Work: Find the solution of equation 54000-5.7967x = 0 .
Question type: Equation
Solution:Original question:
| 54000 | − | 57967 10000 | x | = | 0 |
Transposition :
| - | 57967 10000 | x | = | 0 | − | 54000 |
Combine the items on the right of the equation:
| - | 57967 10000 | x | = | - | 54000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 54000 | = | 57967 10000 | 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 :
57967 10000 | x | = | 54000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 54000 | ÷ | 57967 10000 |
| = | 54000 | × | 10000 57967 |
We obtained :
| x | = | 540000000 57967 |
Convert the result to decimal form :
| x | = | 9315.645108 |
