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:
$$- 12 x = - 13 y - 15$$
Divide both parts of the equation by -12
We get the answer: x = 5/4 + 13*y/12
-12*x+13*y = -15
Looking for similar summands in the left part:
-12*x + 13*y = -15
Move the summands with the other variables
from left part to right part, we given:
$$- 12 x = - 13 y - 15$$
Divide both parts of the equation by -12
x = -15 - 13*y / (-12)
We get the answer: x = 5/4 + 13*y/12

$$x_{1} = \frac{13 \operatorname{re}{\left(y\right)}}{12} + \frac{13 i \operatorname{im}{\left(y\right)}}{12} + \frac{5}{4}$$
x1 = 13*re(y)/12 + 13*i*im(y)/12 + 5/4
