☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation (60%-15%)*x/(1x)*5% = 0 .
Question type: Equation
Solution:Original question:
Remove a bracket on the left of the equation:：
The equation is reduced to :
The equation is reduced to :
The coefficient of the unknown number is reduced to 1 :
We obtained :
However,when simplifying the equation, multiply both sides by ( 1 x ) , and when
, its value is 0. Therefore, the value of this unknown number is not the solution of the equation, and the input to the equation is incorrect.
☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation (60%-15%)*x/(1x)*5% = 0 .
Question type: Equation
Solution:Original question:
| ( | 60 100 | − | 15 100 | ) | x | ÷ | ( | 1 | x | ) | × | 5 100 | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | x | ) |
| ( | 60 100 | − | 15 100 | ) | x | × | 5 100 | = | 0 |
60 100 | x | × | 5 100 | − | 15 100 | x | × | 5 100 | = | 0 |
3 100 | x | − | 3 400 | x | = | 0 |
9 400 | x | = | 0 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 0 | ÷ | 9 400 |
| = | 0 | × | 400 9 |
We obtained :
| x | = | 0 |
| x | = | 0 |
