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:
$$4 x = - 19 y - 13$$
Divide both parts of the equation by 4
We get the answer: x = -13/4 - 19*y/4
4*x+19*y = -13
Looking for similar summands in the left part:
4*x + 19*y = -13
Move the summands with the other variables
from left part to right part, we given:
$$4 x = - 19 y - 13$$
Divide both parts of the equation by 4
x = -13 - 19*y / (4)
We get the answer: x = -13/4 - 19*y/4

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{4} - \frac{19 i \operatorname{im}{\left(y\right)}}{4} - \frac{13}{4}$$
x1 = -19*re(y)/4 - 19*i*im(y)/4 - 13/4
