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:
$$15 x = 13 - 10 y$$
Divide both parts of the equation by 15
We get the answer: x = 13/15 - 2*y/3
15*x+10*y = 13
Looking for similar summands in the left part:
10*y + 15*x = 13
Move the summands with the other variables
from left part to right part, we given:
$$15 x = 13 - 10 y$$
Divide both parts of the equation by 15
x = 13 - 10*y / (15)
We get the answer: x = 13/15 - 2*y/3

$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{3} - \frac{2 i \operatorname{im}{\left(y\right)}}{3} + \frac{13}{15}$$
x1 = -2*re(y)/3 - 2*i*im(y)/3 + 13/15
