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:
$$- 5 x = 13 y - 4$$
Divide both parts of the equation by -5
We get the answer: x = 4/5 - 13*y/5
-5*x-13*y = -4
Looking for similar summands in the left part:
-13*y - 5*x = -4
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 13 y - 4$$
Divide both parts of the equation by -5
x = -4 + 13*y / (-5)
We get the answer: x = 4/5 - 13*y/5

$$x_{1} = - \frac{13 \operatorname{re}{\left(y\right)}}{5} - \frac{13 i \operatorname{im}{\left(y\right)}}{5} + \frac{4}{5}$$
x1 = -13*re(y)/5 - 13*i*im(y)/5 + 4/5
