Work: Find the solution of equation (50-x)/(50-6) = 0.7647 .
Question type: Equation
Solution:Original question:
| ( | 50 | − | x | ) | ÷ | ( | 50 | − | 6 | ) | = | 7647 10000 |
| Multiply both sides of the equation by: | ( | 50 | − | 6 | ) |
| ( | 50 | − | x | ) | = | 7647 10000 | ( | 50 | − | 6 | ) |
| 50 | − | x | = | 7647 10000 | ( | 50 | − | 6 | ) |
| 50 | − | x | = | 7647 10000 | × | 50 | − | 7647 10000 | × | 6 |
| 50 | − | x | = | 7647 200 | − | 22941 5000 |
| 50 | − | x | = | 84117 2500 |
Transposition :
| - | x | = | 84117 2500 | − | 50 |
Combine the items on the right of the equation:
| - | x | = | - | 40883 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
40883 2500 | = | 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 :
| x | = | 40883 2500 |
This is the solution of the equation.
