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:
$$19 x = 12 y - 9$$
Divide both parts of the equation by 19
We get the answer: x = -9/19 + 12*y/19
19*x-12*y = -9
Looking for similar summands in the left part:
-12*y + 19*x = -9
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 12 y - 9$$
Divide both parts of the equation by 19
x = -9 + 12*y / (19)
We get the answer: x = -9/19 + 12*y/19

$$x_{1} = \frac{12 \operatorname{re}{\left(y\right)}}{19} + \frac{12 i \operatorname{im}{\left(y\right)}}{19} - \frac{9}{19}$$
x1 = 12*re(y)/19 + 12*i*im(y)/19 - 9/19
