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:
$$x = - 5 y - 4$$
We get the answer: x = -4 - 5*y
1*x+5*y = -4
Looking for similar summands in the left part:
x + 5*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$x = - 5 y - 4$$
We get the answer: x = -4 - 5*y

x1 = -4 - 5*re(y) - 5*I*im(y)
$$x_{1} = - 5 \operatorname{re}{\left(y\right)} - 5 i \operatorname{im}{\left(y\right)} - 4$$
x1 = -5*re(y) - 5*i*im(y) - 4
