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:
$$- 11 x = - 4 y - 8$$
Divide both parts of the equation by -11
We get the answer: x = 8/11 + 4*y/11
-11*x+4*y = -8
Looking for similar summands in the left part:
-11*x + 4*y = -8
Move the summands with the other variables
from left part to right part, we given:
$$- 11 x = - 4 y - 8$$
Divide both parts of the equation by -11
x = -8 - 4*y / (-11)
We get the answer: x = 8/11 + 4*y/11

8 4*re(y) 4*I*im(y)
x1 = -- + ------- + ---------
11 11 11
$$x_{1} = \frac{4 \operatorname{re}{\left(y\right)}}{11} + \frac{4 i \operatorname{im}{\left(y\right)}}{11} + \frac{8}{11}$$
x1 = 4*re(y)/11 + 4*i*im(y)/11 + 8/11
