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:
$$3 x = 6 y - 5$$
Divide both parts of the equation by 3
We get the answer: x = -5/3 + 2*y
3*x-6*y = -5
Looking for similar summands in the left part:
-6*y + 3*x = -5
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 6 y - 5$$
Divide both parts of the equation by 3
x = -5 + 6*y / (3)
We get the answer: x = -5/3 + 2*y

x1 = -5/3 + 2*re(y) + 2*I*im(y)
$$x_{1} = 2 \operatorname{re}{\left(y\right)} + 2 i \operatorname{im}{\left(y\right)} - \frac{5}{3}$$
x1 = 2*re(y) + 2*i*im(y) - 5/3
