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:
$$- 12 x = - 13 y - 12$$
Divide both parts of the equation by -12
We get the answer: x = 1 + 13*y/12
-12*x+13*y = -12
Looking for similar summands in the left part:
-12*x + 13*y = -12
Move the summands with the other variables
from left part to right part, we given:
$$- 12 x = - 13 y - 12$$
Divide both parts of the equation by -12
x = -12 - 13*y / (-12)
We get the answer: x = 1 + 13*y/12

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