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:
$$15 x = 10 - y$$
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:
$$15 x = 10 - y$$
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
