A system of equations and its solution are given below.
System A
5x-y=-11
3x-2y=-8
Solution: (-2,1)
To get system B below, the second equation in system A was replaced by the sum of that equation and the first equation in system A multiplied by -2.
System B
5x-y=-11
?
A. The second equation in system B is -7x = 14. The solution to system B will be the same as the solution to system A.
B. The second equation in system B is 7x = 30. The solution to system B will be the same as the solution to system A.
C. The second equation in system B is -7x = 14. The solution to system B will not be the same as the solution to system A.
D. The second equation in system B is 7x = 30. The solution to system B will not be the same as the solution to system A.
