WebApr 20, 2015 · 1 Answer Sorted by: 8 If you derive the first equation, you get: X " = a X ′ + b Y ′ (if you are considering a and b as constants). But we have Y ′ = c X + d Y, so substitute in the above equation, you get X " = a X ′ + b ( c X + d Y). Note that Y = 1 b ( X ′ − a X) for b ≠ 0 . So, substituting again you get the final answer.
