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:
$$5 x = - 11 y - 4$$
Divide both parts of the equation by 5
We get the answer: x = -4/5 - 11*y/5
5*x+11*y = -4
Looking for similar summands in the left part:
5*x + 11*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 11 y - 4$$
Divide both parts of the equation by 5
x = -4 - 11*y / (5)
We get the answer: x = -4/5 - 11*y/5

$$x_{1} = - \frac{11 \operatorname{re}{\left(y\right)}}{5} - \frac{11 i \operatorname{im}{\left(y\right)}}{5} - \frac{4}{5}$$
x1 = -11*re(y)/5 - 11*i*im(y)/5 - 4/5
