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:
$$- 7 x = 13 y - 12$$
Divide both parts of the equation by -7
We get the answer: x = 12/7 - 13*y/7
-7*x-13*y = -12
Looking for similar summands in the left part:
-13*y - 7*x = -12
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = 13 y - 12$$
Divide both parts of the equation by -7
x = -12 + 13*y / (-7)
We get the answer: x = 12/7 - 13*y/7

$$x_{1} = - \frac{13 \operatorname{re}{\left(y\right)}}{7} - \frac{13 i \operatorname{im}{\left(y\right)}}{7} + \frac{12}{7}$$
x1 = -13*re(y)/7 - 13*i*im(y)/7 + 12/7
