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:
$$- 4 x = 4 y - 19$$
Divide both parts of the equation by -4
We get the answer: x = 19/4 - y
-4*x-4*y = -19
Looking for similar summands in the left part:
-4*x - 4*y = -19
Move the summands with the other variables
from left part to right part, we given:
$$- 4 x = 4 y - 19$$
Divide both parts of the equation by -4
x = -19 + 4*y / (-4)
We get the answer: x = 19/4 - y
Rapid solution

x1 = 19/4 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + \frac{19}{4}$$
x1 = -re(y) - i*im(y) + 19/4
