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:
$$13 x = - 10 y - 8$$
Divide both parts of the equation by 13
We get the answer: x = -8/13 - 10*y/13
13*x+10*y = -8
Looking for similar summands in the left part:
10*y + 13*x = -8
Move the summands with the other variables
from left part to right part, we given:
$$13 x = - 10 y - 8$$
Divide both parts of the equation by 13
x = -8 - 10*y / (13)
We get the answer: x = -8/13 - 10*y/13

$$x_{1} = - \frac{10 \operatorname{re}{\left(y\right)}}{13} - \frac{10 i \operatorname{im}{\left(y\right)}}{13} - \frac{8}{13}$$
x1 = -10*re(y)/13 - 10*i*im(y)/13 - 8/13
