Work: Find the solution of equation 22000+x/1.05*0.015*1.035+x/1.05*0.2+x/1.05*0.005 = x .
Question type: Equation
Solution:Original question:
| 22000 | + | x | ÷ | 21 20 | × | 3 200 | × | 207 200 | + | x | ÷ | 21 20 | × | 1 5 | + | x | ÷ | 21 20 | × | 1 200 | = | x |
| Left side of the equation = | 22000 | + | x | × | 207 14000 | + | x | × | 4 21 | + | x | × | 1 210 |
| = | 22000 | + | 8821 42000 | x |
| 22000 | + | 8821 42000 | x | = | x |
Transposition :
8821 42000 | x | − | x | = | - | 22000 |
Combine the items on the left of the equation:
| - | 33179 42000 | x | = | - | 22000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 22000 | = | 33179 42000 | 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 :
33179 42000 | x | = | 22000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 22000 | ÷ | 33179 42000 |
| = | 22000 | × | 42000 33179 |
We obtained :
| x | = | 924000000 33179 |
Convert the result to decimal form :
| x | = | 27848.940595 |
