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:
$$19 x = 2 y - 6$$
Divide both parts of the equation by 19
We get the answer: x = -6/19 + 2*y/19
19*x-2*y = -6
Looking for similar summands in the left part:
-2*y + 19*x = -6
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 2 y - 6$$
Divide both parts of the equation by 19
x = -6 + 2*y / (19)
We get the answer: x = -6/19 + 2*y/19

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{19} + \frac{2 i \operatorname{im}{\left(y\right)}}{19} - \frac{6}{19}$$
x1 = 2*re(y)/19 + 2*i*im(y)/19 - 6/19
