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:
$$x = - 11 y - 3$$
We get the answer: x = -3 - 11*y
1*x+11*y = -3
Looking for similar summands in the left part:
x + 11*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$x = - 11 y - 3$$
We get the answer: x = -3 - 11*y

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