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:
-2*y + 8*x = -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
