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:
$$18 x = - 10 y - 16$$
Divide both parts of the equation by 18
We get the answer: x = -8/9 - 5*y/9
18*x+10*y = -16
Looking for similar summands in the left part:
10*y + 18*x = -16
Move the summands with the other variables
from left part to right part, we given:
$$18 x = - 10 y - 16$$
Divide both parts of the equation by 18
x = -16 - 10*y / (18)
We get the answer: x = -8/9 - 5*y/9

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