Help plz Given the system of equations. |--4x+y = 3
12x- y = 12
Which of the options represents the resulting equation after an equivalent expression for yis substituted into the
second equation.
2x - (4 x + 3) = 12
0-4(4 y+) + y=3
O 2 (4 x + 3) - y
0-4x+ 4 x - 3 = 3

Do,h = (7, 9) (14, 18) the scale factor is
