Work: Find the solution of equation (X+8.01+8.07+8.03)/4 = X .
Question type: Equation
Solution:Original question:
| ( | X | + | 801 100 | + | 807 100 | + | 803 100 | ) | ÷ | 4 | = | X |
| Left side of the equation = | X | × | 1 4 | + | 801 100 | × | 1 4 | + | 807 100 | × | 1 4 | + | 803 100 | × | 1 4 |
| = | X | × | 1 4 | + | 801 400 | + | 807 400 | + | 803 400 |
| = | 1 4 | X | + | 2411 400 |
1 4 | X | + | 2411 400 | = | X |
Transposition :
1 4 | X | − | X | = | - | 2411 400 |
Combine the items on the left of the equation:
| - | 3 4 | X | = | - | 2411 400 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2411 400 | = | 3 4 | 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 :
3 4 | X | = | 2411 400 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2411 400 | ÷ | 3 4 |
| = | 2411 400 | × | 4 3 |
| = | 2411 100 | × | 1 3 |
We obtained :
| X | = | 2411 300 |
Convert the result to decimal form :
| X | = | 8.036667 |
