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

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