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:
$$9 x = 18 y + 6$$
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
