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:
$$- 2 x = - 16 y - 7$$
Divide both parts of the equation by -2
We get the answer: x = 7/2 + 8*y
-2*x+16*y = -7
Looking for similar summands in the left part:
-2*x + 16*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = - 16 y - 7$$
Divide both parts of the equation by -2
x = -7 - 16*y / (-2)
We get the answer: x = 7/2 + 8*y

x1 = 7/2 + 8*re(y) + 8*I*im(y)
$$x_{1} = 8 \operatorname{re}{\left(y\right)} + 8 i \operatorname{im}{\left(y\right)} + \frac{7}{2}$$
x1 = 8*re(y) + 8*i*im(y) + 7/2
