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:
$$6 x = - 11 y - 20$$
Divide both parts of the equation by 6
We get the answer: x = -10/3 - 11*y/6
6*x+11*y = -20
Looking for similar summands in the left part:
6*x + 11*y = -20
Move the summands with the other variables
from left part to right part, we given:
$$6 x = - 11 y - 20$$
Divide both parts of the equation by 6
x = -20 - 11*y / (6)
We get the answer: x = -10/3 - 11*y/6

$$x_{1} = - \frac{11 \operatorname{re}{\left(y\right)}}{6} - \frac{11 i \operatorname{im}{\left(y\right)}}{6} - \frac{10}{3}$$
x1 = -11*re(y)/6 - 11*i*im(y)/6 - 10/3
