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:
$$3 x = - 6 y - 6$$
Divide both parts of the equation by 3
We get the answer: x = -2 - 2*y
3*x+6*y = -6
Looking for similar summands in the left part:
3*x + 6*y = -6
Move the summands with the other variables
from left part to right part, we given:
$$3 x = - 6 y - 6$$
Divide both parts of the equation by 3
x = -6 - 6*y / (3)
We get the answer: x = -2 - 2*y

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