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

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