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:
$$- 8 x = 2 y - 11$$
Divide both parts of the equation by -8
We get the answer: x = 11/8 - y/4
-8*x-2*y = -11
Looking for similar summands in the left part:
-8*x - 2*y = -11
Move the summands with the other variables
from left part to right part, we given:
$$- 8 x = 2 y - 11$$
Divide both parts of the equation by -8
x = -11 + 2*y / (-8)
We get the answer: x = 11/8 - y/4

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