Work: Find the solution of equation 1+x = （1-6.4%）（1+x+8x） .
Question type: Equation
Solution:Original question:
| 1 | + | x | = | ( | 1 | − | 32 500 | ) | ( | 1 | + | x | + | 8 | x | ) |
| Right side of the equation = | 1 | ( | 1 | + | x | + | 8 | x | ) | − | 32 500 | ( | 1 | + | x | + | 8 | x | ) |
| = | 1 | × | 1 | + | 1 | x | + | 1 | × | 8 | x | − | 32 500 | ( | 1 | + | x | + | 8 | x | ) |
| = | 1 | + | 1 | x | + | 8 | x | − | 32 500 | ( | 1 | + | x | + | 8 | x | ) |
| = | 1 | + | 9 | x | − | 32 500 | ( | 1 | + | x | + | 8 | x | ) |
| = | 1 | + | 9 | x | − | 32 500 | × | 1 | − | 32 500 | x | − | 32 500 | × | 8 | x |
| = | 1 | + | 9 | x | − | 8 125 | − | 32 500 | x | − | 64 125 | x |
| = | 117 125 | + | 1053 125 | x |
| 1 | + | x | = | 117 125 | + | 1053 125 | x |
Transposition :
| x | − | 1053 125 | x | = | 117 125 | − | 1 |
Combine the items on the left of the equation:
| - | 928 125 | x | = | 117 125 | − | 1 |
Combine the items on the right of the equation:
| - | 928 125 | x | = | - | 8 125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
8 125 | = | 928 125 | 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 :
928 125 | x | = | 8 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 8 125 | ÷ | 928 125 |
| = | 8 125 | × | 125 928 |
| = | 1 | × | 1 116 |
We obtained :
| x | = | 1 116 |
Convert the result to decimal form :
| x | = | 0.008621 |
