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:
$$- 13 x = 14 y$$
Divide both parts of the equation by -13
We get the answer: x = -14*y/13
-13*x-14*y = 0
Looking for similar summands in the left part:
-14*y - 13*x = 0
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 14 y$$
Divide both parts of the equation by -13
x = 14*y / (-13)
We get the answer: x = -14*y/13

14*re(y) 14*I*im(y)
x1 = - -------- - ----------
13 13
$$x_{1} = - \frac{14 \operatorname{re}{\left(y\right)}}{13} - \frac{14 i \operatorname{im}{\left(y\right)}}{13}$$
x1 = -14*re(y)/13 - 14*i*im(y)/13
