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:
$$15 x = - 9 y - 6$$
Divide both parts of the equation by 15
We get the answer: x = -2/5 - 3*y/5
15*x+9*y = -6
Looking for similar summands in the left part:
9*y + 15*x = -6
Move the summands with the other variables
from left part to right part, we given:
$$15 x = - 9 y - 6$$
Divide both parts of the equation by 15
x = -6 - 9*y / (15)
We get the answer: x = -2/5 - 3*y/5

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{5} - \frac{3 i \operatorname{im}{\left(y\right)}}{5} - \frac{2}{5}$$
x1 = -3*re(y)/5 - 3*i*im(y)/5 - 2/5
