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:
$$- 13 x = 6 y + 13$$
Divide both parts of the equation by -13
We get the answer: x = -1 - 6*y/13
-13*x-6*y = 13
Looking for similar summands in the left part:
-13*x - 6*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 6 y + 13$$
Divide both parts of the equation by -13
x = 13 + 6*y / (-13)
We get the answer: x = -1 - 6*y/13

x1 = -1 - ------- - ---------
13 13
$$x_{1} = - \frac{6 \operatorname{re}{\left(y\right)}}{13} - \frac{6 i \operatorname{im}{\left(y\right)}}{13} - 1$$
x1 = -6*re(y)/13 - 6*i*im(y)/13 - 1
