1) (Choice D) Replace one equation with the sum/difference of both equations
2) (Choice B) No
System A:
\begin{cases}5x+y=3\\\\4x-7y=8\end{cases}
System B:
\begin{cases}5x+y=3\\\\x+8y=-5\end{cases}
1) How can we get System B from System A?
(Choice A) Replace one equation with itself where a quantity is added to only one side
(Choice B) Replace one equation with itself where the same quantity is added to both sides
(Choice C) Replace only the right-hand side of one equation with the sum/difference of the right-hand sides of both equations
(Choice D) Replace one equation with the sum/difference of both equations
2) Based on the previous answer, are the systems equivalent? In other words, do they have the same solution?
(Choice A) Yes
(Choice B) No
