Answer two questions about Systems A and B: A: x−4y=1
5x+6y=−5
B: x=1+4y
5x+6y=−5
How can we get System B from System A?
A: Replace one equation with itself where a quantity is added to only one side
B: Replace one equation with itself where the same quantity is added to both sides
C: Swap only the right-hand sides of both equations
D: Swap the order of the equations

Based on the previous answer, are the systems equivalent? In other words, do they have the same solution?
A: Yes
B: No
