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:
$$- 10 x = y - 11$$
Divide both parts of the equation by -10
We get the answer: x = 11/10 - y/10
-10*x-1*y = -11
Looking for similar summands in the left part:
-y - 10*x = -11
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = y - 11$$
Divide both parts of the equation by -10
x = -11 + y / (-10)
We get the answer: x = 11/10 - y/10

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{10} - \frac{i \operatorname{im}{\left(y\right)}}{10} + \frac{11}{10}$$
x1 = -re(y)/10 - i*im(y)/10 + 11/10
