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:
$$13 x = - 15 y - 6$$
Divide both parts of the equation by 13
We get the answer: x = -6/13 - 15*y/13
13*x+15*y = -6
Looking for similar summands in the left part:
13*x + 15*y = -6
Move the summands with the other variables
from left part to right part, we given:
$$13 x = - 15 y - 6$$
Divide both parts of the equation by 13
x = -6 - 15*y / (13)
We get the answer: x = -6/13 - 15*y/13

$$x_{1} = - \frac{15 \operatorname{re}{\left(y\right)}}{13} - \frac{15 i \operatorname{im}{\left(y\right)}}{13} - \frac{6}{13}$$
x1 = -15*re(y)/13 - 15*i*im(y)/13 - 6/13
