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:
$$2 y = - 2 x$$
Divide both parts of the equation by 2
We get the answer: y = -x
2*x+2*y = 0
Looking for similar summands in the left part:
2*x + 2*y = 0
Move the summands with the other variables
from left part to right part, we given:
$$2 y = - 2 x$$
Divide both parts of the equation by 2
y = -2*x / (2)
We get the answer: y = -x

y1 = -re(x) - I*im(x)
$$y_{1} = - \operatorname{re}{\left(x\right)} - i \operatorname{im}{\left(x\right)}$$
y1 = -re(x) - i*im(x)
Sum and product of roots

sum
-re(x) - I*im(x)
$$- \operatorname{re}{\left(x\right)} - i \operatorname{im}{\left(x\right)}$$
=
-re(x) - I*im(x)
$$- \operatorname{re}{\left(x\right)} - i \operatorname{im}{\left(x\right)}$$
product
-re(x) - I*im(x)
$$- \operatorname{re}{\left(x\right)} - i \operatorname{im}{\left(x\right)}$$
=
-re(x) - I*im(x)
$$- \operatorname{re}{\left(x\right)} - i \operatorname{im}{\left(x\right)}$$
