Answer 1

From -2x+4y = -2, we must find 2x = 10. This is done by multiplying x - y = 3 by 4 to get 4x - 4y = 12, and adding the -2x + 4y = -2.
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 (is) the same as the solution to system A.
