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:
$$- 2 x = 13 - 6 y$$
Divide both parts of the equation by -2
We get the answer: x = -13/2 + 3*y
-2*x+6*y = 13
Looking for similar summands in the left part:
-2*x + 6*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 13 - 6 y$$
Divide both parts of the equation by -2
x = 13 - 6*y / (-2)
We get the answer: x = -13/2 + 3*y

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