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

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