-2*(-2 - y) - y - 2 = 0
$$\left(- y - 2 \left(- y - 2\right)\right) - 2 = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$y = -2$$
We get the answer: y = -2
-2*(-2-y)-y-2 = 0
Expand brackets in the left part
2*2+2*y-y-2 = 0
Looking for similar summands in the left part:
2 + y = 0
Move free summands (without y)
from left part to right part, we given:
$$y = -2$$
We get the answer: y = -2
