Work: Find the solution of equation （20+x）×0.466 = 1.428×x .
Question type: Equation
Solution:Original question:
| ( | 20 | + | x | ) | × | 233 500 | = | 357 250 | x |
| Left side of the equation = | 20 | × | 233 500 | + | x | × | 233 500 |
| = | 233 25 | + | x | × | 233 500 |
233 25 | + | 233 500 | x | = | 357 250 | x |
Transposition :
233 500 | x | − | 357 250 | x | = | - | 233 25 |
Combine the items on the left of the equation:
| - | 481 500 | x | = | - | 233 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
233 25 | = | 481 500 | 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 :
481 500 | x | = | 233 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 233 25 | ÷ | 481 500 |
| = | 233 25 | × | 500 481 |
| = | 233 | × | 20 481 |
We obtained :
| x | = | 4660 481 |
Convert the result to decimal form :
| x | = | 9.68815 |
