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:
$$- 12 x = 2 y + 16$$
Divide both parts of the equation by -12
We get the answer: x = -4/3 - y/6
-12*x-2*y = 16
Looking for similar summands in the left part:
-12*x - 2*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 12 x = 2 y + 16$$
Divide both parts of the equation by -12
x = 16 + 2*y / (-12)
We get the answer: x = -4/3 - y/6

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{6} - \frac{i \operatorname{im}{\left(y\right)}}{6} - \frac{4}{3}$$
x1 = -re(y)/6 - i*im(y)/6 - 4/3
