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:
$$8 x = - 3 y - 4$$
Divide both parts of the equation by 8
We get the answer: x = -1/2 - 3*y/8
8*x+3*y = -4
Looking for similar summands in the left part:
3*y + 8*x = -4
Move the summands with the other variables
from left part to right part, we given:
$$8 x = - 3 y - 4$$
Divide both parts of the equation by 8
x = -4 - 3*y / (8)
We get the answer: x = -1/2 - 3*y/8

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{8} - \frac{3 i \operatorname{im}{\left(y\right)}}{8} - \frac{1}{2}$$
x1 = -3*re(y)/8 - 3*i*im(y)/8 - 1/2
