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:
$$- 13 x = 2 y + 2$$
Divide both parts of the equation by -13
We get the answer: x = -2/13 - 2*y/13
-13*x-2*y = 2
Looking for similar summands in the left part:
-13*x - 2*y = 2
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 2 y + 2$$
Divide both parts of the equation by -13
x = 2 + 2*y / (-13)
We get the answer: x = -2/13 - 2*y/13

$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{13} - \frac{2 i \operatorname{im}{\left(y\right)}}{13} - \frac{2}{13}$$
x1 = -2*re(y)/13 - 2*i*im(y)/13 - 2/13
