Work: Find the solution of equation （X+8.82+8.66+9.30）/4 = X .
Question type: Equation
Solution:Original question:
| ( | X | + | 441 50 | + | 433 50 | + | 93 10 | ) | ÷ | 4 | = | X |
| Left side of the equation = | X | × | 1 4 | + | 441 50 | × | 1 4 | + | 433 50 | × | 1 4 | + | 93 10 | × | 1 4 |
| = | X | × | 1 4 | + | 441 200 | + | 433 200 | + | 93 40 |
| = | 1 4 | X | + | 1339 200 |
1 4 | X | + | 1339 200 | = | X |
Transposition :
1 4 | X | − | X | = | - | 1339 200 |
Combine the items on the left of the equation:
| - | 3 4 | X | = | - | 1339 200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1339 200 | = | 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 | = | 1339 200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1339 200 | ÷ | 3 4 |
| = | 1339 200 | × | 4 3 |
| = | 1339 50 | × | 1 3 |
We obtained :
| X | = | 1339 150 |
Convert the result to decimal form :
| X | = | 8.926667 |
