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:
$$- 3 x = - 3 y - 9$$
Divide both parts of the equation by -3
We get the answer: x = 3 + y
-3*x+3*y = -9
Looking for similar summands in the left part:
-3*x + 3*y = -9
Move the summands with the other variables
from left part to right part, we given:
$$- 3 x = - 3 y - 9$$
Divide both parts of the equation by -3
x = -9 - 3*y / (-3)
We get the answer: x = 3 + y

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