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:
$$12 x = - 3 y - 2$$
Divide both parts of the equation by 12
We get the answer: x = -1/6 - y/4
12*x+3*y = -2
Looking for similar summands in the left part:
3*y + 12*x = -2
Move the summands with the other variables
from left part to right part, we given:
$$12 x = - 3 y - 2$$
Divide both parts of the equation by 12
x = -2 - 3*y / (12)
We get the answer: x = -1/6 - y/4

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