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

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{10} - \frac{i \operatorname{im}{\left(y\right)}}{10} + \frac{1}{10}$$
x1 = -re(y)/10 - i*im(y)/10 + 1/10
