[ 1/1 Equation]
Work: Find the solution of equation 2(x-2)-(3x-1) = 2(1-x) .
Question type: Equation
Solution:Original question:
| 2 | ( | x | − | 2 | ) | − | ( | 3 | x | − | 1 | ) | = | 2 | ( | 1 | − | x | ) |
| Left side of the equation = | 2 | x | − | 2 | × | 2 | − | ( | 3 | x | − | 1 | ) |
| = | 2 | x | − | 4 | − | ( | 3 | x | − | 1 | ) |
| = | 2 | x | − | 4 | − | 3 | x | + | 1 |
| = | - | 1 | x | − | 3 |
| - | 1 | x | − | 3 | = | 2 | ( | 1 | − | x | ) |
| Right side of the equation = | 2 | × | 1 | − | 2 | x |
| = | 2 | − | 2 | x |
| - | 1 | x | − | 3 | = | 2 | − | 2 | x |
Transposition :
| - | 1 | x | + | 2 | x | = | 2 | + | 3 |
| x | = | 2 | + | 3 |
Combine the items on the left of the equation:
| x | = | 2 | + | 3 |
Combine the items on the right of the equation:
| x | = | 5 |
This is the solution of the equation.
