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:
$$20 x = - 18 y - 9$$
Divide both parts of the equation by 20
We get the answer: x = -9/20 - 9*y/10
20*x+18*y = -9
Looking for similar summands in the left part:
18*y + 20*x = -9
Move the summands with the other variables
from left part to right part, we given:
$$20 x = - 18 y - 9$$
Divide both parts of the equation by 20
x = -9 - 18*y / (20)
We get the answer: x = -9/20 - 9*y/10

$$x_{1} = - \frac{9 \operatorname{re}{\left(y\right)}}{10} - \frac{9 i \operatorname{im}{\left(y\right)}}{10} - \frac{9}{20}$$
x1 = -9*re(y)/10 - 9*i*im(y)/10 - 9/20
