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:
$$18 x = 11 y + 2$$
Divide both parts of the equation by 18
We get the answer: x = 1/9 + 11*y/18
18*x-11*y = 2
Looking for similar summands in the left part:
-11*y + 18*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 11 y + 2$$
Divide both parts of the equation by 18
x = 2 + 11*y / (18)
We get the answer: x = 1/9 + 11*y/18

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{18} + \frac{11 i \operatorname{im}{\left(y\right)}}{18} + \frac{1}{9}$$
x1 = 11*re(y)/18 + 11*i*im(y)/18 + 1/9
