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:
$$5 x = 5 y + 20$$
Divide both parts of the equation by 5
We get the answer: x = 4 + y
5*x-5*y = 20
Looking for similar summands in the left part:
-5*y + 5*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 5 y + 20$$
Divide both parts of the equation by 5
x = 20 + 5*y / (5)
We get the answer: x = 4 + y
Rapid solution

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