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:
$$5 x = - 19 y - 3$$
Divide both parts of the equation by 5
We get the answer: x = -3/5 - 19*y/5
5*x+19*y = -3
Looking for similar summands in the left part:
5*x + 19*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 19 y - 3$$
Divide both parts of the equation by 5
x = -3 - 19*y / (5)
We get the answer: x = -3/5 - 19*y/5

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{5} - \frac{19 i \operatorname{im}{\left(y\right)}}{5} - \frac{3}{5}$$
x1 = -19*re(y)/5 - 19*i*im(y)/5 - 3/5
