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:
$$14 x = - 5 y - 1$$
Divide both parts of the equation by 14
We get the answer: x = -1/14 - 5*y/14
14*x+5*y = -1
Looking for similar summands in the left part:
5*y + 14*x = -1
Move the summands with the other variables
from left part to right part, we given:
$$14 x = - 5 y - 1$$
Divide both parts of the equation by 14
x = -1 - 5*y / (14)
We get the answer: x = -1/14 - 5*y/14

$$x_{1} = - \frac{5 \operatorname{re}{\left(y\right)}}{14} - \frac{5 i \operatorname{im}{\left(y\right)}}{14} - \frac{1}{14}$$
x1 = -5*re(y)/14 - 5*i*im(y)/14 - 1/14
