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

$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{2} + \frac{5 i \operatorname{im}{\left(y\right)}}{2} + \frac{11}{2}$$
x1 = 5*re(y)/2 + 5*i*im(y)/2 + 11/2
