[ 1/1 Equation]
Work: Find the solution of equation 3x-4.5x（1/6-x） = 0 .
Question type: Equation
Solution:Original question:
| 3 | x | − | 9 2 | x | ( | 1 | ÷ | 6 | − | x | ) | = | 0 |
| Left side of the equation = | 3 | x | − | 9 2 | x | × | 1 | ÷ | 6 | + | 9 2 | x | x |
| = | 3 | x | − | 3 4 | x | + | 9 2 | x | x |
| = | 9 4 | x | + | 9 2 | x | x |
9 4 | x | + | 9 2 | x | x | = | 0 |
After the equation is converted into a general formula, it is converted into:
( 2x + 1 )( x +0 )=0
From
2x + 1 = 0
x + 0 = 0
it is concluded that:：
| x1= | - | 1 2 |
| x2=0 |
There are 2 solution(s).
