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:
-15*y - 9*x = -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
