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:
$$- 18 x = - 8 y - 3$$
Divide both parts of the equation by -18
We get the answer: x = 1/6 + 4*y/9
-18*x+8*y = -3
Looking for similar summands in the left part:
-18*x + 8*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = - 8 y - 3$$
Divide both parts of the equation by -18
x = -3 - 8*y / (-18)
We get the answer: x = 1/6 + 4*y/9

$$x_{1} = \frac{4 \operatorname{re}{\left(y\right)}}{9} + \frac{4 i \operatorname{im}{\left(y\right)}}{9} + \frac{1}{6}$$
x1 = 4*re(y)/9 + 4*i*im(y)/9 + 1/6
