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:
$$19 x = 17 - 2 y$$
Divide both parts of the equation by 19
We get the answer: x = 17/19 - 2*y/19
19*x+2*y = 17
Looking for similar summands in the left part:
2*y + 19*x = 17
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 17 - 2 y$$
Divide both parts of the equation by 19
x = 17 - 2*y / (19)
We get the answer: x = 17/19 - 2*y/19

$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{19} - \frac{2 i \operatorname{im}{\left(y\right)}}{19} + \frac{17}{19}$$
x1 = -2*re(y)/19 - 2*i*im(y)/19 + 17/19
