Work: Find the solution of equation ((2.33+0.66)/2-X)/(2.33-0.66) = -0.45 .
Question type: Equation
Solution:Original question:
| ( | ( | 233 100 | + | 33 50 | ) | ÷ | 2 | − | X | ) | ÷ | ( | 233 100 | − | 33 50 | ) | = | - | 9 20 |
| Multiply both sides of the equation by: | ( | 233 100 | − | 33 50 | ) |
| ( | ( | 233 100 | + | 33 50 | ) | ÷ | 2 | − | X | ) | = | - | 9 20 | ( | 233 100 | − | 33 50 | ) |
| ( | 233 100 | + | 33 50 | ) | ÷ | 2 | − | X | = | - | 9 20 | ( | 233 100 | − | 33 50 | ) |
| ( | 233 100 | + | 33 50 | ) | ÷ | 2 | − | X | = | - | 9 20 | × | 233 100 | + | 9 20 | × | 33 50 |
| ( | 233 100 | + | 33 50 | ) | × | 1 2 | − | X | = | - | 2097 2000 | + | 297 1000 |
| ( | 233 100 | + | 33 50 | ) | × | 1 2 | − | X | = | - | 1503 2000 |
233 100 | × | 1 2 | + | 33 50 | × | 1 2 | − | X | = | - | 1503 2000 |
233 200 | + | 33 100 | − | X | = | - | 1503 2000 |
299 200 | − | X | = | - | 1503 2000 |
Transposition :
| - | X | = | - | 1503 2000 | − | 299 200 |
Combine the items on the right of the equation:
| - | X | = | - | 4493 2000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
4493 2000 | = | 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 | = | 4493 2000 |
This is the solution of the equation.
