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:
$$x = y + 1$$
We get the answer: x = 1 + y
x-y = 1
Looking for similar summands in the left part:
x - y = 1
Move the summands with the other variables
from left part to right part, we given:
$$x = y + 1$$
We get the answer: x = 1 + y

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

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