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:
$$2 x = - 6 y - 2$$
Divide both parts of the equation by 2
We get the answer: x = -1 - 3*y
2*x+6*y = -2
Looking for similar summands in the left part:
2*x + 6*y = -2
Move the summands with the other variables
from left part to right part, we given:
$$2 x = - 6 y - 2$$
Divide both parts of the equation by 2
x = -2 - 6*y / (2)
We get the answer: x = -1 - 3*y

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