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:
$$4 x = - 12 y - 11$$
Divide both parts of the equation by 4
We get the answer: x = -11/4 - 3*y
4*x+12*y = -11
Looking for similar summands in the left part:
4*x + 12*y = -11
Move the summands with the other variables
from left part to right part, we given:
$$4 x = - 12 y - 11$$
Divide both parts of the equation by 4
x = -11 - 12*y / (4)
We get the answer: x = -11/4 - 3*y

x1 = -11/4 - 3*re(y) - 3*I*im(y)
$$x_{1} = - 3 \operatorname{re}{\left(y\right)} - 3 i \operatorname{im}{\left(y\right)} - \frac{11}{4}$$
x1 = -3*re(y) - 3*i*im(y) - 11/4
