Work: Find the solution of equation ((4.53+17.85)/2-X)/(17.85-4.53) = 0.45 .
Question type: Equation
Solution:Original question:
| ( | ( | 453 100 | + | 357 20 | ) | ÷ | 2 | − | X | ) | ÷ | ( | 357 20 | − | 453 100 | ) | = | 9 20 |
| Multiply both sides of the equation by: | ( | 357 20 | − | 453 100 | ) |
| ( | ( | 453 100 | + | 357 20 | ) | ÷ | 2 | − | X | ) | = | 9 20 | ( | 357 20 | − | 453 100 | ) |
| ( | 453 100 | + | 357 20 | ) | ÷ | 2 | − | X | = | 9 20 | ( | 357 20 | − | 453 100 | ) |
| ( | 453 100 | + | 357 20 | ) | ÷ | 2 | − | X | = | 9 20 | × | 357 20 | − | 9 20 | × | 453 100 |
| ( | 453 100 | + | 357 20 | ) | × | 1 2 | − | X | = | 3213 400 | − | 4077 2000 |
| ( | 453 100 | + | 357 20 | ) | × | 1 2 | − | X | = | 2997 500 |
453 100 | × | 1 2 | + | 357 20 | × | 1 2 | − | X | = | 2997 500 |
453 200 | + | 357 40 | − | X | = | 2997 500 |
1119 100 | − | X | = | 2997 500 |
Transposition :
| - | X | = | 2997 500 | − | 1119 100 |
Combine the items on the right of the equation:
| - | X | = | - | 1299 250 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1299 250 | = | 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 | = | 1299 250 |
This is the solution of the equation.
