I’m missing the rest of the second line (no equals sign). Which do you mean? Here are the two likely interpretations and results — pick the one you intended:
1) You want to simplify the expression x + y + 2 given y = x + 2:
x + y + 2 = x + (x + 2) + 2 = 2x + 4.
2) You meant the system
y = x + 2
x + y + 2 = 0
Substitute y: x + (x + 2) + 2 = 0 ⇒ 2x + 4 = 0 ⇒ x = −2, y = 0.
3) More generally, if x + y + 2 = c, then substituting y = x + 2 gives 2x + 4 = c ⇒ x = (c − 4)/2 and y = c/2.
Tell me which case you meant (or paste the full second equation) and I’ll proceed.
