Work: Find the solution of equation 22000+x/1.05*0.015+x/1.05*0.015*0.07*0.5+x/1.05*1.035*0.02+x/1.05*1.035*0.005 = x .
Question type: Equation
Solution:Original question:
| 22000 | + | x | ÷ | 21 20 | × | 3 200 | + | x | ÷ | 21 20 | × | 3 200 | × | 7 100 | × | 1 2 | + | x | ÷ | 21 20 | × | 207 200 | = | x |
| Left side of the equation = | 22000 | + | x | × | 1 70 | + | x | × | 1 2000 | + | x | × | 69 3500 | + | x | × | 69 14000 |
| = | 22000 | + | 69 1750 | x |
| 22000 | + | 69 1750 | x | = | x |
Transposition :
69 1750 | x | − | x | = | - | 22000 |
Combine the items on the left of the equation:
| - | 1681 1750 | x | = | - | 22000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 22000 | = | 1681 1750 | 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 :
1681 1750 | x | = | 22000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 22000 | ÷ | 1681 1750 |
| = | 22000 | × | 1750 1681 |
We obtained :
| x | = | 38500000 1681 |
Convert the result to decimal form :
| x | = | 22903.033908 |
