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:
$$15 x = - 5 y - 5$$
Divide both parts of the equation by 15
We get the answer: x = -1/3 - y/3
15*x+5*y = -5
Looking for similar summands in the left part:
5*y + 15*x = -5
Move the summands with the other variables
from left part to right part, we given:
$$15 x = - 5 y - 5$$
Divide both parts of the equation by 15
x = -5 - 5*y / (15)
We get the answer: x = -1/3 - y/3

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