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:
$$- 11 x = 11 y + 4$$
Divide both parts of the equation by -11
We get the answer: x = -4/11 - y
-11*x-11*y = 4
Looking for similar summands in the left part:
-11*x - 11*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 11 x = 11 y + 4$$
Divide both parts of the equation by -11
x = 4 + 11*y / (-11)
We get the answer: x = -4/11 - y
Rapid solution

x1 = -4/11 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} - \frac{4}{11}$$
x1 = -re(y) - i*im(y) - 4/11
