Question 1142809: Find a single translation that has the same effect as each composition of translations. (x, y) → (x - 7, y + 8) followed by (x, y) → (x + 5, y - 6).
1. (x,y)→(x - 1,y - 1)
2. (x,y)→(x - 13,y - 14)
3. (x,y)→(x - 12,y - 14)
4. (x,y)→(x - 2,y+2)

Both transformations are simply rigid translations in the plane.
The first shifts left by 7 and the second shifts right by 5; the result is a shift left by 2.
The first shifts up by 8 and the second shifts down by 6; the result is a shift up by 2.
So the combination gives the translation "left 2, up 2".
Which answer choice is that?
