Step-by-step explanation:
Given
--- (1)
--- (2)
Required
Select equations with same solution
Add equation (1) to (2)
--- (1)
--- (2)
_________________
Factorize:
--- (3)
So, a system of (1) and (3) can be represented as:
This means (a) has the same solution.
Another possible solution is as follows:
Subtract equation (1) from (2)
--- (2)
--- (1)
_________________
Factorize
--- (4)
So, a system of (2) and (4) can be represented as:
This means (c) has the same solution.
