Work: Find the solution of equation (9535+40+x)*1.8% = 4x .
Question type: Equation
Solution:Original question:
| ( | 9535 | + | 40 | + | x | ) | × | 9 500 | = | 4 | x |
| Left side of the equation = | 9535 | × | 9 500 | + | 40 | × | 9 500 | + | x | × | 9 500 |
| = | 17163 100 | + | 18 25 | + | x | × | 9 500 |
| = | 3447 20 | + | 9 500 | x |
3447 20 | + | 9 500 | x | = | 4 | x |
Transposition :
9 500 | x | − | 4 | x | = | - | 3447 20 |
Combine the items on the left of the equation:
| - | 1991 500 | x | = | - | 3447 20 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3447 20 | = | 1991 500 | 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 :
1991 500 | x | = | 3447 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3447 20 | ÷ | 1991 500 |
| = | 3447 20 | × | 500 1991 |
| = | 3447 | × | 25 1991 |
We obtained :
| x | = | 86175 1991 |
Convert the result to decimal form :
| x | = | 43.28227 |
