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:
$$8 x = 13 y - 12$$
Divide both parts of the equation by 8
We get the answer: x = -3/2 + 13*y/8
8*x-13*y = -12
Looking for similar summands in the left part:
-13*y + 8*x = -12
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 13 y - 12$$
Divide both parts of the equation by 8
x = -12 + 13*y / (8)
We get the answer: x = -3/2 + 13*y/8

$$x_{1} = \frac{13 \operatorname{re}{\left(y\right)}}{8} + \frac{13 i \operatorname{im}{\left(y\right)}}{8} - \frac{3}{2}$$
x1 = 13*re(y)/8 + 13*i*im(y)/8 - 3/2
