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:
$$5 x = - 6 y - 8$$
Divide both parts of the equation by 5
We get the answer: x = -8/5 - 6*y/5
5*x+6*y = -8
Looking for similar summands in the left part:
5*x + 6*y = -8
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 6 y - 8$$
Divide both parts of the equation by 5
x = -8 - 6*y / (5)
We get the answer: x = -8/5 - 6*y/5

$$x_{1} = - \frac{6 \operatorname{re}{\left(y\right)}}{5} - \frac{6 i \operatorname{im}{\left(y\right)}}{5} - \frac{8}{5}$$
x1 = -6*re(y)/5 - 6*i*im(y)/5 - 8/5
