The solution

You have entered [src]
x + y = 5
$$x + y = 5$$
Detail solution
Given the linear equation:
x+y = 5

Looking for similar summands in the left part:
x + y = 5

Move the summands with the other variables
from left part to right part, we given:
$$x = 5 - y$$
We get the answer: x = 5 - y

Sum and product of roots [src]
sum
5 - re(y) - I*im(y)
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 5$$
=
5 - re(y) - I*im(y)
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 5$$
product
5 - re(y) - I*im(y)
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 5$$
=
5 - re(y) - I*im(y)
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 5$$
5 - re(y) - i*im(y)
Rapid solution [src]
x1 = 5 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 5$$
x1 = -re(y) - i*im(y) + 5
