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:
$$9 x = y + 17$$
Divide both parts of the equation by 9
We get the answer: x = 17/9 + y/9
9*x-1*y = 17
Looking for similar summands in the left part:
-y + 9*x = 17
Move the summands with the other variables
from left part to right part, we given:
$$9 x = y + 17$$
Divide both parts of the equation by 9
x = 17 + y / (9)
We get the answer: x = 17/9 + y/9

x1 = -- + ----- + -------
9 9 9
$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{9} + \frac{i \operatorname{im}{\left(y\right)}}{9} + \frac{17}{9}$$
x1 = re(y)/9 + i*im(y)/9 + 17/9
