Ответ:
if it was negative it could be solve like that
X^2 - 16=
(x+4)(x-4)
x^2 -4x+4x-16
then the -4x and the +4x would cancelled out and you would left with:
x^2-16.
since it is positive it cannot be factored.
~hope i helped.

Answer
–3x + 3y = 6
Explanation
We need to simplify each expression to see which one is similar to x – y = –2.
–3x + 3y = 6
multiply by 1/3 on both sides.
1/3( –3x + 3y) = 6 × 1/3
⇒ -x + y = 2
Multiply by -1 on both sides.
-1( –x + y) = 2 ×-1
⇒ x - y = -2
