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:
$$- x = 5 y - 4$$
Divide both parts of the equation by -1
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:
$$- x = 5 y - 4$$
Divide both parts of the equation by -1
x = -4 + 5*y / (-1)
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
