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:
$$19 x = - 19 y - 4$$
Divide both parts of the equation by 19
We get the answer: x = -4/19 - y
19*x+19*y = -4
Looking for similar summands in the left part:
19*x + 19*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$19 x = - 19 y - 4$$
Divide both parts of the equation by 19
x = -4 - 19*y / (19)
We get the answer: x = -4/19 - y
Rapid solution

x1 = -4/19 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} - \frac{4}{19}$$
x1 = -re(y) - i*im(y) - 4/19
