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:
$$9 x = 8 y + 6$$
Divide both parts of the equation by 9
We get the answer: x = 2/3 + 8*y/9
9*x-8*y = 6
Looking for similar summands in the left part:
-8*y + 9*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 8 y + 6$$
Divide both parts of the equation by 9
x = 6 + 8*y / (9)
We get the answer: x = 2/3 + 8*y/9

$$x_{1} = \frac{8 \operatorname{re}{\left(y\right)}}{9} + \frac{8 i \operatorname{im}{\left(y\right)}}{9} + \frac{2}{3}$$
x1 = 8*re(y)/9 + 8*i*im(y)/9 + 2/3
