Work: Find the solution of equation (x+8000)/1.06*0.06*1.12 = x .
Question type: Equation
Solution:Original question:
| ( | x | + | 8000 | ) | ÷ | 53 50 | × | 3 50 | × | 28 25 | = | x |
| Left side of the equation = | ( | x | + | 8000 | ) | × | 84 1325 |
| ( | x | + | 8000 | ) | × | 84 1325 | = | x |
| Left side of the equation = | x | × | 84 1325 | + | 8000 | × | 84 1325 |
| = | x | × | 84 1325 | + | 26880 53 |
84 1325 | x | + | 26880 53 | = | x |
Transposition :
84 1325 | x | − | x | = | - | 26880 53 |
Combine the items on the left of the equation:
| - | 1241 1325 | x | = | - | 26880 53 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
26880 53 | = | 1241 1325 | 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 :
1241 1325 | x | = | 26880 53 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 26880 53 | ÷ | 1241 1325 |
| = | 26880 53 | × | 1325 1241 |
| = | 26880 | × | 25 1241 |
We obtained :
| x | = | 672000 1241 |
Convert the result to decimal form :
| x | = | 541.498791 |
