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:
$$20 x = 11 - 10 y$$
Divide both parts of the equation by 20
We get the answer: x = 11/20 - y/2
20*x+10*y = 11
Looking for similar summands in the left part:
10*y + 20*x = 11
Move the summands with the other variables
from left part to right part, we given:
$$20 x = 11 - 10 y$$
Divide both parts of the equation by 20
x = 11 - 10*y / (20)
We get the answer: x = 11/20 - y/2

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{2} - \frac{i \operatorname{im}{\left(y\right)}}{2} + \frac{11}{20}$$
x1 = -re(y)/2 - i*im(y)/2 + 11/20
