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:
$$2 x = 11 - 16 y$$
Divide both parts of the equation by 2
We get the answer: x = 11/2 - 8*y
2*x+16*y = 11
Looking for similar summands in the left part:
2*x + 16*y = 11
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 11 - 16 y$$
Divide both parts of the equation by 2
x = 11 - 16*y / (2)
We get the answer: x = 11/2 - 8*y

x1 = 11/2 - 8*re(y) - 8*I*im(y)
$$x_{1} = - 8 \operatorname{re}{\left(y\right)} - 8 i \operatorname{im}{\left(y\right)} + \frac{11}{2}$$
x1 = -8*re(y) - 8*i*im(y) + 11/2
