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:
$$4 x = 11 y - 2$$
Divide both parts of the equation by 4
We get the answer: x = -1/2 + 11*y/4
4*x-11*y = -2
Looking for similar summands in the left part:
-11*y + 4*x = -2
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 11 y - 2$$
Divide both parts of the equation by 4
x = -2 + 11*y / (4)
We get the answer: x = -1/2 + 11*y/4

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{4} + \frac{11 i \operatorname{im}{\left(y\right)}}{4} - \frac{1}{2}$$
x1 = 11*re(y)/4 + 11*i*im(y)/4 - 1/2
