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:
$$18 x = 11 y - 11$$
Divide both parts of the equation by 18
We get the answer: x = -11/18 + 11*y/18
18*x-11*y = -11
Looking for similar summands in the left part:
-11*y + 18*x = -11
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 11 y - 11$$
Divide both parts of the equation by 18
x = -11 + 11*y / (18)
We get the answer: x = -11/18 + 11*y/18

11 11*re(y) 11*I*im(y)
x1 = - -- + -------- + ----------
18 18 18
$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{18} + \frac{11 i \operatorname{im}{\left(y\right)}}{18} - \frac{11}{18}$$
x1 = 11*re(y)/18 + 11*i*im(y)/18 - 11/18
