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:
$$- 5 x = - 5 y - 9$$
Divide both parts of the equation by -5
We get the answer: x = 9/5 + y
-5*x+5*y = -9
Looking for similar summands in the left part:
-5*x + 5*y = -9
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = - 5 y - 9$$
Divide both parts of the equation by -5
x = -9 - 5*y / (-5)
We get the answer: x = 9/5 + y
Rapid solution

x1 = 9/5 + I*im(y) + re(y)
$$x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} + \frac{9}{5}$$
x1 = re(y) + i*im(y) + 9/5
