Concept explainers
(a)
The two equations
No, the two equations are equivalent.
Given:
The equations,
Concept used:
- The two equations are said to be equivalent when they have the same solution set.
Calculation:
In order to determine the two equations are equivalent or not, first solving first equation and then solving the second one, if they have same solution then these equations are equivalent as shown below:
So, both the equations have different solution, therefore the two equations are not equivalent.
(b)
The two equations
Yes, the two equations are equivalent.
Given:
The equations,
