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:
$$13 x = - 5 y - 16$$
Divide both parts of the equation by 13
We get the answer: x = -16/13 - 5*y/13
13*x+5*y = -16
Looking for similar summands in the left part:
5*y + 13*x = -16
Move the summands with the other variables
from left part to right part, we given:
$$13 x = - 5 y - 16$$
Divide both parts of the equation by 13
x = -16 - 5*y / (13)
We get the answer: x = -16/13 - 5*y/13

$$x_{1} = - \frac{5 \operatorname{re}{\left(y\right)}}{13} - \frac{5 i \operatorname{im}{\left(y\right)}}{13} - \frac{16}{13}$$
x1 = -5*re(y)/13 - 5*i*im(y)/13 - 16/13
