Answer 2

Answer:

$\boxed{\text{a) y = -2}}\\\\\boxed{\text{b) x - y = 4}}$

Step-by-step explanation:

$\boxed{\text{x + y = 0}}\\\\\text{Given that x = 2}\\\\\text{Therefore, y + 2 = 0}\\\\\boxed{\text{Answer a): y = -2}}\\\\\text{Now, we must find x - y}\\\\\text{We know y = -2 and x = 2}\\\\\text{Hence, x - y = 2 - (-2) = 2 + 2 = 4}\\\\\boxed{\text{Answer b): x - y = 4}}$
