Just subtract the 1st equation from the 2nd, as follows:

<span>  3x+6y=33
-(</span>3x+4y=19)
-----------------
         2y= 14, and y = 7.   Sub 7 for y in either of the original equations to obtain the value of x.  Write your answer in the form  (x, 7).

Answer:

  (x, y) ⇒ (x -m, y -n)

Step-by-step explanation:

Reverse the arrow and solve for the x and y on the left:

  (x +m, y +n) ⇒ (x, y)

This resolves to two relations:

  x + m ⇒ x

  x ⇒ x - m . . . . . subtract m

and

  y + n ⇒ y

  y ⇒ y - n . . . . . . subtract n

Putting these back together, we have ...

  (x, y) ⇒ (x -m, y -n) . . . . . maps P'Q' to PQ

_____

The original translation was right m and up n. The reverse translation is left m and down n. That is what the rule shows.
