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:
$$- 18 x = 16 - 5 y$$
Divide both parts of the equation by -18
We get the answer: x = -8/9 + 5*y/18
-18*x+5*y = 16
Looking for similar summands in the left part:
-18*x + 5*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 16 - 5 y$$
Divide both parts of the equation by -18
x = 16 - 5*y / (-18)
We get the answer: x = -8/9 + 5*y/18

x1 = - - + ------- + ---------
9 18 18
$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{18} + \frac{5 i \operatorname{im}{\left(y\right)}}{18} - \frac{8}{9}$$
x1 = 5*re(y)/18 + 5*i*im(y)/18 - 8/9
