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:
$$- 15 x = y + 10$$
Divide both parts of the equation by -15
We get the answer: x = -2/3 - y/15
-15*x-1*y = 10
Looking for similar summands in the left part:
-y - 15*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = y + 10$$
Divide both parts of the equation by -15
x = 10 + y / (-15)
We get the answer: x = -2/3 - y/15

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