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:
$$- 16 x = 8 y + 2$$
Divide both parts of the equation by -16
We get the answer: x = -1/8 - y/2
-16*x-8*y = 2
Looking for similar summands in the left part:
-16*x - 8*y = 2
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 8 y + 2$$
Divide both parts of the equation by -16
x = 2 + 8*y / (-16)
We get the answer: x = -1/8 - y/2

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{2} - \frac{i \operatorname{im}{\left(y\right)}}{2} - \frac{1}{8}$$
x1 = -re(y)/2 - i*im(y)/2 - 1/8
