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:
$$- 9 x = 12 y - 19$$
Divide both parts of the equation by -9
We get the answer: x = 19/9 - 4*y/3
-9*x-12*y = -19
Looking for similar summands in the left part:
-12*y - 9*x = -19
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = 12 y - 19$$
Divide both parts of the equation by -9
x = -19 + 12*y / (-9)
We get the answer: x = 19/9 - 4*y/3

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{3} - \frac{4 i \operatorname{im}{\left(y\right)}}{3} + \frac{19}{9}$$
x1 = -4*re(y)/3 - 4*i*im(y)/3 + 19/9
