4 A system of equations and its solution are given below.
System A
23 - y = 3
33 + 4y = 10
Solution: (2,1)
Choose the correct option that explains what steps were followed to obtain the system of equations below.
System B
21 - y = 3
11. = 22
. A
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation
multiplied by 4. The solution to system B will be the same as the solution to system A
B To get system B, the second equation in system A was replaced by the sum of that equation and the first equation
multiplied by 3. The solution to system B will not be the same as the solution to system A
C. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation
multiplied by -4. The solution to system B will not be the same as the solution to system A
D To get system B, the second equation in system A was replaced by the sum of that equation and the first equation
multiplied by 2. The solution to system B will be the same as the solution to system A
