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

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