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:
-15*y + 13*x = -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

x1 = - -- + -------- + ----------
13 13 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
