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:
$$16 x = 7 y + 8$$
Divide both parts of the equation by 16
We get the answer: x = 1/2 + 7*y/16
16*x-7*y = 8
Looking for similar summands in the left part:
-7*y + 16*x = 8
Move the summands with the other variables
from left part to right part, we given:
$$16 x = 7 y + 8$$
Divide both parts of the equation by 16
x = 8 + 7*y / (16)
We get the answer: x = 1/2 + 7*y/16

$$x_{1} = \frac{7 \operatorname{re}{\left(y\right)}}{16} + \frac{7 i \operatorname{im}{\left(y\right)}}{16} + \frac{1}{2}$$
x1 = 7*re(y)/16 + 7*i*im(y)/16 + 1/2
