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:
$$- 18 x = 17 - 12 y$$
Divide both parts of the equation by -18
We get the answer: x = -17/18 + 2*y/3
-18*x+12*y = 17
Looking for similar summands in the left part:
-18*x + 12*y = 17
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 17 - 12 y$$
Divide both parts of the equation by -18
x = 17 - 12*y / (-18)
We get the answer: x = -17/18 + 2*y/3

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{3} + \frac{2 i \operatorname{im}{\left(y\right)}}{3} - \frac{17}{18}$$
x1 = 2*re(y)/3 + 2*i*im(y)/3 - 17/18
