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:
$$- 19 x = 3 y - 1$$
Divide both parts of the equation by -19
We get the answer: x = 1/19 - 3*y/19
-19*x-3*y = -1
Looking for similar summands in the left part:
-19*x - 3*y = -1
Move the summands with the other variables
from left part to right part, we given:
$$- 19 x = 3 y - 1$$
Divide both parts of the equation by -19
x = -1 + 3*y / (-19)
We get the answer: x = 1/19 - 3*y/19

19 19 19
$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{19} - \frac{3 i \operatorname{im}{\left(y\right)}}{19} + \frac{1}{19}$$
x1 = -3*re(y)/19 - 3*i*im(y)/19 + 1/19
