Answer:

Step-by-step explanation:

To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.

Just that the respective sides need to have the same ratio.

Note, if it was from B to A, it'd be 1/4.

X = 4y - 18

-3(4y - 18) + 12y =54
-12y + 54 + 12y = 54
54 = 54
