Step-by-step explanation:
See Attachment for complete question
To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;
Given that
Testing Option A
Substitute
and 
in 
Open Brackets
Substitute
and 
in 
Open Brackets
In both cases, the expression on the right hand side equates to that on the left hand side;
Hence, there's no need to check for other options.
