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:
$$18 x = 18 - 12 y$$
Divide both parts of the equation by 18
We get the answer: x = 1 - 2*y/3
18*x+12*y = 18
Looking for similar summands in the left part:
12*y + 18*x = 18
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 18 - 12 y$$
Divide both parts of the equation by 18
x = 18 - 12*y / (18)
We get the answer: x = 1 - 2*y/3

$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{3} - \frac{2 i \operatorname{im}{\left(y\right)}}{3} + 1$$
x1 = -2*re(y)/3 - 2*i*im(y)/3 + 1
