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:
$$11 x = - 19 y$$
Divide both parts of the equation by 11
We get the answer: x = -19*y/11
11*x+19*y = 0
Looking for similar summands in the left part:
11*x + 19*y = 0
Move the summands with the other variables
from left part to right part, we given:
$$11 x = - 19 y$$
Divide both parts of the equation by 11
x = -19*y / (11)
We get the answer: x = -19*y/11

11 11
$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{11} - \frac{19 i \operatorname{im}{\left(y\right)}}{11}$$
x1 = -19*re(y)/11 - 19*i*im(y)/11
