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:
$$- 9 x = - 15 y - 17$$
Divide both parts of the equation by -9
We get the answer: x = 17/9 + 5*y/3
-9*x+15*y = -17
Looking for similar summands in the left part:
-9*x + 15*y = -17
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = - 15 y - 17$$
Divide both parts of the equation by -9
x = -17 - 15*y / (-9)
We get the answer: x = 17/9 + 5*y/3

$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{3} + \frac{5 i \operatorname{im}{\left(y\right)}}{3} + \frac{17}{9}$$
x1 = 5*re(y)/3 + 5*i*im(y)/3 + 17/9
