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:
$$5 x = - 13 y - 1$$
Divide both parts of the equation by 5
We get the answer: x = -1/5 - 13*y/5
5*x+13*y = -1
Looking for similar summands in the left part:
5*x + 13*y = -1
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 13 y - 1$$
Divide both parts of the equation by 5
x = -1 - 13*y / (5)
We get the answer: x = -1/5 - 13*y/5

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