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

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