To get System B from System A, we need to perform specific operations on the equations in System A. Let's go step by step:
1) Notice that both System A and System B have the same equations. They are written in different orders, but they have the same structure.
2) To rearrange System A into System B, we can switch the positions of the equations.
3) Let's switch the first and second equations:
-4x - 6y = 9 (equation 1)
3x + y = -4 (equation 2)
4) Now, let's switch the third and fourth equations:
-4x - 6y = 9 (equation 1)
-x - 5y = 5 (equation 2)
By performing these steps, we have transformed System A into System B
