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*y + 12*x = -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 + I*im(y) + re(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
