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:
$$9 x = 6 - 18 y$$
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:
9*x + 18*y = 6
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 6 - 18 y$$
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
