The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$x - y = -2$$
Move the summands with the other variables
from left part to right part, we given:
$$x = y + -2$$
We get the answer: x = -2 + y
x-y+2 = 0
Looking for similar summands in the left part:
2 + x - y = 0
Move free summands (without x)
from left part to right part, we given:
$$x - y = -2$$
Move the summands with the other variables
from left part to right part, we given:
$$x = y + -2$$
We get the answer: x = -2 + y

sum
-2 + I*im(y) + re(y)
$$\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
=
-2 + I*im(y) + re(y)
$$\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
product
-2 + I*im(y) + re(y)
$$\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
=
-2 + I*im(y) + re(y)
$$\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
-2 + i*im(y) + re(y)
Rapid solution

x1 = -2 + I*im(y) + re(y)
$$x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
x1 = re(y) + i*im(y) - 2
