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:
$$15 x = 5 - 9 y$$
Divide both parts of the equation by 15
We get the answer: x = 1/3 - 3*y/5
15*x+9*y = 5
Looking for similar summands in the left part:
9*y + 15*x = 5
Move the summands with the other variables
from left part to right part, we given:
$$15 x = 5 - 9 y$$
Divide both parts of the equation by 15
x = 5 - 9*y / (15)
We get the answer: x = 1/3 - 3*y/5

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