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:
-16*y + 18*x = 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

x1 = - + ------- + ---------
9 9 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
