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:
$$19 x = - 8 y - 3$$
Divide both parts of the equation by 19
We get the answer: x = -3/19 - 8*y/19
19*x+8*y = -3
Looking for similar summands in the left part:
8*y + 19*x = -3
Move the summands with the other variables
from left part to right part, we given:
$$19 x = - 8 y - 3$$
Divide both parts of the equation by 19
x = -3 - 8*y / (19)
We get the answer: x = -3/19 - 8*y/19

$$x_{1} = - \frac{8 \operatorname{re}{\left(y\right)}}{19} - \frac{8 i \operatorname{im}{\left(y\right)}}{19} - \frac{3}{19}$$
x1 = -8*re(y)/19 - 8*i*im(y)/19 - 3/19
