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:
$$10 x = 2 y + 11$$
Divide both parts of the equation by 10
We get the answer: x = 11/10 + y/5
10*x-2*y = 11
Looking for similar summands in the left part:
-2*y + 10*x = 11
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 2 y + 11$$
Divide both parts of the equation by 10
x = 11 + 2*y / (10)
We get the answer: x = 11/10 + y/5

10 5 5
$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{5} + \frac{i \operatorname{im}{\left(y\right)}}{5} + \frac{11}{10}$$
x1 = re(y)/5 + i*im(y)/5 + 11/10
