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:
$$- 18 x = 16 y + 4$$
Divide both parts of the equation by -18
We get the answer: x = -2/9 - 8*y/9
-18*x-16*y = 4
Looking for similar summands in the left part:
-18*x - 16*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 16 y + 4$$
Divide both parts of the equation by -18
x = 4 + 16*y / (-18)
We get the answer: x = -2/9 - 8*y/9

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