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:
$$6 x = 9 - 12 y$$
Divide both parts of the equation by 6
We get the answer: x = 3/2 - 2*y
6*x+12*y = 9
Looking for similar summands in the left part:
6*x + 12*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 9 - 12 y$$
Divide both parts of the equation by 6
x = 9 - 12*y / (6)
We get the answer: x = 3/2 - 2*y

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