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:
$$5 x = 20 - 5 y$$
Divide both parts of the equation by 5
We get the answer: x = 4 - y
5*x+5*y = 20
Looking for similar summands in the left part:
5*x + 5*y = 20
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 20 - 5 y$$
Divide both parts of the equation by 5
x = 20 - 5*y / (5)
We get the answer: x = 4 - y
Rapid solution

x1 = 4 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
x1 = -re(y) - i*im(y) + 4
