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:

$$9 x = 18 y + 6$$

Divide both parts of the equation by 9

We get the answer: x = 2/3 + 2*y

9*x-18*y = 6

Looking for similar summands in the left part:

-18*y + 9*x = 6

Move the summands with the other variables

from left part to right part, we given:

$$9 x = 18 y + 6$$

Divide both parts of the equation by 9

x = 6 + 18*y / (9)

We get the answer: x = 2/3 + 2*y

x1 = 2/3 + 2*re(y) + 2*I*im(y)

$$x_{1} = 2 \operatorname{re}{\left(y\right)} + 2 i \operatorname{im}{\left(y\right)} + \frac{2}{3}$$

x1 = 2*re(y) + 2*i*im(y) + 2/3
