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:
$$x = y + 2$$
We get the answer: x = 2 + y
x-y = 2
Looking for similar summands in the left part:
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)
$$\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} + 2$$
