To determine which pair of linear equations has the same solution set, let's solve each pair of equations:
-
First Pair:
Expanding and simplifying:The second equation is:
Both variables yield
, but this does not mean both equations have the same solution set, as they are independent equations. -
Second Pair:
The second equation:
These have different solutions (
). -
Third Pair:
The second equation:
Different solutions (
). -
Fourth Pair:
The second equation:
Again, different solutions (
).
Conclusion: Each pair resulted in different values for their respective variables. Therefore, none of the pairs have the same solution set. However, if we are strictly identifying pairs based on the question format, Pair 1 does yield
Further review shows none match
Thus, if we are looking for a definitive answer, consider that no pairs yield the same solution set directly, leaving us to infer Pair 1 or to reconvene on strict comparisons of all statements initially until an option might distinctly show it.
