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*y + 19*x = -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 + I*im(y) + re(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
