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:
$$- 13 x = 19 y + 15$$
Divide both parts of the equation by -13
We get the answer: x = -15/13 - 19*y/13
-13*x-19*y = 15
Looking for similar summands in the left part:
-19*y - 13*x = 15
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 19 y + 15$$
Divide both parts of the equation by -13
x = 15 + 19*y / (-13)
We get the answer: x = -15/13 - 19*y/13

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{13} - \frac{19 i \operatorname{im}{\left(y\right)}}{13} - \frac{15}{13}$$
x1 = -19*re(y)/13 - 19*i*im(y)/13 - 15/13
