Work: Find the solution of equation (0.3X-1173.75)/500 = (0.3X-1353.75)/750 .
Question type: Equation
Solution:Original question:
| ( | 3 10 | X | − | 4695 4 | ) | ÷ | 500 | = | ( | 3 10 | X | − | 5415 4 | ) | ÷ | 750 |
| Left side of the equation = | 3 10 | X | × | 1 500 | − | 4695 4 | × | 1 500 |
| = | 3 5000 | X | − | 939 400 |
3 5000 | X | − | 939 400 | = | ( | 3 10 | X | − | 5415 4 | ) | ÷ | 750 |
| Right side of the equation = | 3 10 | X | × | 1 750 | − | 5415 4 | × | 1 750 |
| = | 1 2500 | X | − | 361 200 |
3 5000 | X | − | 939 400 | = | 1 2500 | X | − | 361 200 |
Transposition :
3 5000 | X | − | 1 2500 | X | = | - | 361 200 | + | 939 400 |
Combine the items on the left of the equation:
1 5000 | X | = | - | 361 200 | + | 939 400 |
Combine the items on the right of the equation:
1 5000 | X | = | 217 400 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 217 400 | ÷ | 1 5000 |
| = | 217 400 | × | 5000 |
| = | 217 2 | × | 25 |
We obtained :
| X | = | 5425 2 |
Convert the result to decimal form :
| X | = | 2712.5 |
