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:
$$- 4 x = 19 - 4 y$$
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:
$$- 4 x = 19 - 4 y$$
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 + I*im(y) + re(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
