Work: Find the solution of equation （20-3.223）×60+（0.213×18） = x .
Question type: Equation
Solution:Original question:
| ( | 20 | − | 3223 1000 | ) | × | 60 | + | ( | 213 1000 | × | 18 | ) | = | x |
| Left side of the equation = | 20 | × | 60 | − | 3223 1000 | × | 60 | + | ( | 213 1000 | × | 18 | ) |
| = | 1200 | − | 9669 50 | + | ( | 213 1000 | × | 18 | ) |
| = | 50331 50 | + | ( | 213 1000 | × | 18 | ) |
| = | 50331 50 | + | 213 1000 | × | 18 |
| = | 50331 50 | + | 1917 500 |
| = | 505227 500 |
505227 500 | = | x |
Transposition :
| - | x | = | - | 505227 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
505227 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 :
| x | = | 505227 500 |
This is the solution of the equation.
