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

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