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:
$$- 18 x = 6 y - 1$$
Divide both parts of the equation by -18
We get the answer: x = 1/18 - y/3
-18*x-6*y = -1
Looking for similar summands in the left part:
-18*x - 6*y = -1
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 6 y - 1$$
Divide both parts of the equation by -18
x = -1 + 6*y / (-18)
We get the answer: x = 1/18 - y/3

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{3} - \frac{i \operatorname{im}{\left(y\right)}}{3} + \frac{1}{18}$$
x1 = -re(y)/3 - i*im(y)/3 + 1/18
