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:
$$13 x = 19 - 12 y$$
Divide both parts of the equation by 13
We get the answer: x = 19/13 - 12*y/13
13*x+12*y = 19
Looking for similar summands in the left part:
12*y + 13*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$13 x = 19 - 12 y$$
Divide both parts of the equation by 13
x = 19 - 12*y / (13)
We get the answer: x = 19/13 - 12*y/13

$$x_{1} = - \frac{12 \operatorname{re}{\left(y\right)}}{13} - \frac{12 i \operatorname{im}{\left(y\right)}}{13} + \frac{19}{13}$$
x1 = -12*re(y)/13 - 12*i*im(y)/13 + 19/13
