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:
$$5 x = - 4 y - 12$$
Divide both parts of the equation by 5
We get the answer: x = -12/5 - 4*y/5
5*x+4*y = -12
Looking for similar summands in the left part:
4*y + 5*x = -12
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 4 y - 12$$
Divide both parts of the equation by 5
x = -12 - 4*y / (5)
We get the answer: x = -12/5 - 4*y/5

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{5} - \frac{4 i \operatorname{im}{\left(y\right)}}{5} - \frac{12}{5}$$
x1 = -4*re(y)/5 - 4*i*im(y)/5 - 12/5
