Work: Find the solution of equation （（X-500）*（1-25%））/1280 = （（X-260）*（1-25%））/1189 .
Question type: Equation
Solution:Original question:
| ( | ( | X | − | 500 | ) | ( | 1 | − | 25 100 | ) | ) | ÷ | 1280 | = | ( | ( | X | − | 260 | ) | ( | 1 | − | 25 100 | ) | ) | ÷ | 1189 |
| Left side of the equation = | ( | X | − | 500 | ) | ( | 1 | − | 25 100 | ) | × | 1 1280 |
| = | X | ( | 1 | − | 25 100 | ) | × | 1 1280 | − | 500 | ( | 1 | − | 25 100 | ) | × | 1 1280 |
| = | X | ( | 1 | − | 25 100 | ) | × | 1 1280 | − | 25 64 | ( | 1 | − | 25 100 | ) |
| = | X | × | 1 | × | 1 1280 | − | X | × | 25 100 | × | 1 1280 | − | 25 64 | ( | 1 | − | 25 100 | ) |
| = | X | × | 1 1280 | − | X | × | 1 5120 | − | 25 64 | ( | 1 | − | 25 100 | ) |
| = | 3 5120 | X | − | 25 64 | ( | 1 | − | 25 100 | ) |
| = | 3 5120 | X | − | 25 64 | × | 1 | + | 25 64 | × | 25 100 |
| = | 3 5120 | X | − | 25 64 | + | 25 256 |
| = | 3 5120 | X | − | 75 256 |
3 5120 | X | − | 75 256 | = | ( | ( | X | − | 260 | ) | ( | 1 | − | 25 100 | ) | ) | ÷ | 1189 |
| Right side of the equation = | ( | X | − | 260 | ) | ( | 1 | − | 25 100 | ) | × | 1 1189 |
| = | X | ( | 1 | − | 25 100 | ) | × | 1 1189 | − | 260 | ( | 1 | − | 25 100 | ) | × | 1 1189 |
| = | X | ( | 1 | − | 25 100 | ) | × | 1 1189 | − | 260 1189 | ( | 1 | − | 25 100 | ) |
| = | X | × | 1 | × | 1 1189 | − | X | × | 25 100 | × | 1 1189 | − | 260 1189 | ( | 1 | − | 25 100 | ) |
| = | X | × | 1 1189 | − | X | × | 1 4756 | − | 260 1189 | ( | 1 | − | 25 100 | ) |
| = | 3 4756 | X | − | 260 1189 | ( | 1 | − | 25 100 | ) |
| = | 3 4756 | X | − | 260 1189 | × | 1 | + | 260 1189 | × | 25 100 |
| = | 3 4756 | X | − | 260 1189 | + | 65 1189 |
| = | 3 4756 | X | − | 195 1189 |
3 5120 | X | − | 75 256 | = | 3 4756 | X | − | 195 1189 |
Transposition :
3 5120 | X | − | 3 4756 | X | = | - | 195 1189 | + | 75 256 |
Combine the items on the left of the equation:
| - | 273 6087680 | X | = | - | 195 1189 | + | 75 256 |
Combine the items on the right of the equation:
| - | 273 6087680 | X | = | 39255 304384 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 39255 304384 | = | 273 6087680 | 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 :
273 6087680 | X | = | - | 39255 304384 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 39255 304384 | ÷ | 273 6087680 |
| = | - | 39255 304384 | × | 6087680 273 |
| = | - | 13085 | × | 20 91 |
We obtained :
| X | = | - | 261700 91 |
Convert the result to decimal form :
| X | = | - 2875.824176 |
