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:
2*y + 16*x = 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
