The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$x = y$$
We get the answer: x = y
x-y = 0
Looking for similar summands in the left part:
x - y = 0
Move the summands with the other variables
from left part to right part, we given:
$$x = y$$
We get the answer: x = y

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

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