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:
$$14 x = - 3 y - 4$$
Divide both parts of the equation by 14
We get the answer: x = -2/7 - 3*y/14
14*x+3*y = -4
Looking for similar summands in the left part:
3*y + 14*x = -4
Move the summands with the other variables
from left part to right part, we given:
$$14 x = - 3 y - 4$$
Divide both parts of the equation by 14
x = -4 - 3*y / (14)
We get the answer: x = -2/7 - 3*y/14

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{14} - \frac{3 i \operatorname{im}{\left(y\right)}}{14} - \frac{2}{7}$$
x1 = -3*re(y)/14 - 3*i*im(y)/14 - 2/7
