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:
$$2 x = 4 - 8 y$$
Divide both parts of the equation by 2
We get the answer: x = 2 - 4*y
2*x+8*y = 4
Looking for similar summands in the left part:
2*x + 8*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 4 - 8 y$$
Divide both parts of the equation by 2
x = 4 - 8*y / (2)
We get the answer: x = 2 - 4*y

x1 = 2 - 4*re(y) - 4*I*im(y)
$$x_{1} = - 4 \operatorname{re}{\left(y\right)} - 4 i \operatorname{im}{\left(y\right)} + 2$$
x1 = -4*re(y) - 4*i*im(y) + 2
