Work: Find the solution of equation 50 = 0.5x-26.67 .
Question type: Equation
Solution:Original question:
| 50 | = | 1 2 | x | − | 2667 100 |
Transposition :
| - | 1 2 | x | = | - | 2667 100 | − | 50 |
Combine the items on the right of the equation:
| - | 1 2 | x | = | - | 7667 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
7667 100 | = | 1 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 :
1 2 | x | = | 7667 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7667 100 | ÷ | 1 2 |
| = | 7667 100 | × | 2 |
| = | 7667 50 | × | 1 |
We obtained :
| x | = | 7667 50 |
Convert the result to decimal form :
| x | = | 153.34 |
