WILL GIVE BRAINLIEST! 30 points for brainliest Please help, my toughest question on my final.

A system of equations and its solution are given below.

System A
x-y=3
-2x+4y=-2

Complete the sentences to explain what steps were followed to obtain the system of equations below.

System B
x-y=3
2x=10

To get system B, the (second, first) equation in system A was replaced by the sum of that equation and the (second, first) equation multiplied by (-3, 2, 4) The solution to system B (is, is not) the same as the solution to system A.
